Experimental procedures for ADME and PK studies.

Solubility. Solubility assays were carried out on a Biomek FX lab automation workstation

(Beckman Coulter, Inc., Fullerton, CA) using µSOL Evolution software (pION Inc., Woburn,

MA). The detailed method is described as follows. 10 µL of 10 mM compound stock (in DMSO)

was added to 190 µL 1-propanol to make a reference stock plate. 5 µL from this reference stock

plate were mixed with 70 µL 1-propanol and 75 µL citrate phosphate-buffered saline (PBS;

isotonic) to make the reference plate, and the UV spectrum (250-500 nm) of the reference plate

was read. 6 µL of 10 mM test compound stock was added to 594 µL buffer in a 96-well storage

plate and mixed. The storage plate was sealed and incubated at RT for 18 h. The suspension was

then filtered through a 96-well filter plate (pION Inc., Woburn, MA). 75 µL of filtrate was mixed

with 75 µL 1-propanol to make the sample plate, and the UV spectrum of the sample plate was

read. Calculations were carried out with µSOL Evolution software based on the area under the

curve (AUC) of the UV spectrum of the sample and reference plates. All compounds were tested

in triplicate.

Permeability. Our parallel artificial membrane permeability assay (PAMPA) was conducted

with a Biomek FX lab automation workstation (Beckman Coulter, Inc., Fullerton, CA) and

PAMPA Evolution 96 Command software (pION Inc., Woburn, MA). The detailed method is

described as follows: 3 µL of 10 µM test compound stock in DMSO was mixed with 597 µL of

citrate PBS (isotonic) to make a diluted test compound. 150 µL of diluted test compound was

transferred to a UV plate (pION Inc., Woburn, MA), and the UV spectrum of this reference plate

was read. The membrane, on a pre-loaded PAMPA Sandwich (pION Inc., Woburn, MA), was

painted with 4 µL of GIT lipid (pION Inc., Woburn, MA). The acceptor chamber was then filled

with 200 µL of ASB (acceptor solution buffer, pION Inc., Woburn, MA), and the donor chamber

was filled with 180 µL of diluted test compound. The PAMPA Sandwich was assembled, placed

on the Gut-box, and stirred for 30 min. The aqueous boundary layer was set to 40 µm for stirring.

The UV spectrum (250-500 nm) of the donor and the acceptor were read. The permeability

coefficient was calculated using PAMPA Evolution 96 Command software based on the AUC of

the reference plate, the donor plate, and the acceptor plate. All compounds were tested in

triplicate.

Plasma stability. Compound stocks were at a concentration of 10 mM in DMSO. The internal

standard was 10 µM warfarin in methanol. 1.9 mL of mouse plasma (Fisher Scientific) or pooled

human plasma (Innovative Research Inc) were added to columns 1, 4, 7, and 10 of a 2 mL 96-

well deep well plate (pION Inc., Woburn, MA, catalog #110023); this was the master plate. 1.9

µL of compound stock were added to each well with plasmas and mixed well. Using a multi-

channel pipette, 600 µL from columns 1, 4, 7, and 10 were taken and added into the rest of the

columns (fluids in column 1 were added to columns 2 and 3, column 4 to 5 and 6, etc.). From the

master plate, 65 µL was taken from each well and added into eight storage plates (pION Inc.,

Woburn, MA, catalog #110323), each for a different time point. The storage plates were then

incubated at 37 ºC and shaken at 60 rpm. Samples were taken at 0 min, 30 min, 1 h, 2 h, 4 h, 8 h,

24 h, and 48h. At each time point, 195 µL of internal standard was added to quench the reaction.

The plates were then centrifuged at 4000 rpm for 15 min, and supernatant was analyzed by Ultra

High Pressure Liquid Chromatography with Mass Spectrometry (UPLC-MS; Waters Inc.,

Milford, MA). The compound was detected by selected ion recording (SIR), and quantitation

was based on the peak area ratio of the test compound vs. the internal standard.

Simulated gastric fluid (SGF) stability. Compound stocks were at a concentration of 10 mM in

DMSO. The internal standard was 10 µM warfarin in methanol. 1.4 mL of concentrated HCl

(37%), 0.4 g of NaCl, and 0.64 g of pepsin were added to 198 mL of deionized water to make

SGF (pH 1). 1.9 mL of SGF were added to columns 1, 4, 7, and 10 of a 2 mL 96-well deep well

plate; this was the master plate. 1.9 µL of compound stock was added to each well with SGF and

mixed well. Using a multi-channel pipette, 600 µL from columns 1, 4, 7, and 10 was taken and

added into the rest of the columns (fluids in column 1 were added to columns 2 and 3, column 4

to 5 and 6, etc.). From the master plate, 65 µL was taken from each well and added into eight

storage plates, each for a different time point. The storage plates was then incubated at 37 ºC and

shaken at 60 rpm. Samples were taken at 0 min, 30 min, 1 h, 2 h, 4 h, 8 h, 24 h, and 48h. At each

time point, 195 µL of internal standard was added to quench the reaction. The plates were then

centrifuged at 4000 rpm for 15 min, and supernatant was analyzed by UPLC-MS. The compound

was detected by SIR, and quantitation was based on the peak area ratio of the test compound vs.

the internal standard.

PBS stability. Compound stocks were at a concentration of 10 mM in DMSO. The internal

standard was 10 µM warfarin in methanol. 1.9 mL of PBS (Mediatech Inc., Manassas, VA,

catalog #21-040-CM) were added to columns 1, 4, 7, and 10 of a 2 mL 96-well deep well plate;

this was the master plate. 1.9 µL of compound stock were added to each well with SGF and

mixed well. Using a multi-channel pipette, 600 µL from columns 1, 4, 7, and 10 was taken and

added into the rest of the columns (fluids in column 1 were added to columns 2 and 3, column 4

to 5 and 6, etc.). From the master plate, 65 µL was taken from each well and added into eight

storage plates, each for a different time point. The storage plates were then incubated at 37 ºC

and shaken at 60 rpm. Samples were taken at 0 min, 30 min, 1 h, 2 h, 4 h, 8 h, 24 h, and 48 h. At

each time point, 195 µL of internal standard was added to quench the reaction. The plates were

then centrifuged at 4000 rpm for 15 min, and supernatant was analyzed by UPLC-MS. The

compound was detected by SIR, and quantitation was based on the peak area ratio of the test

compound vs. the internal standard.

Liver microsomal stability. 1.582 mL of mouse liver microsome (20 mg/mL, female CD-1

mice, pooled; Fisher Scientific, catalog #NC9567486) were mixed with 0.127 mL of 0.5 M

EDTA solution and 48.3 mL of potassium phosphate buffer (0.1 M, pH 7.4, 37 °C) to make 50

mL of mouse liver microsome solution. Human liver microsomal solution was made in the same

way with human liver microsome (50 pooled mix gender; Fisher Scientific, catalog #50-722-

516). One volume of 10 mM DMSO compound stock was mixed with four volumes of

acetonitrile to make 2 mM diluted compound stock in DMSO and acetonitrile. 37.83 µL of

diluted compound stock was added to 3 mL of liver microsomal solution and vortexed to make

microsomal solution with compound. 1 mL of liver microsomal solution with compound was

added to each well of a master storage plate (pION Inc., Woburn, MA, catalog #110323). All

compounds were added in triplicate. Mouse and human liver microsomes were tested side by

Page 4: 2376479 File000001 40983185

side on the same plate. 175 µL of each well was dispensed from the master plate into five storage

plates. For 0 h time point, 450 µL of pre-cooled (4 ºC) internal standard (10 µM warfarin in

methanol) was added to the first plate before the reaction started. 5.25 mL of microsome assay

solution A (Fisher Scientific, catalog #NC9255727) was combined with 1.05 mL of solution B

(Fisher Scientific, catalog #NC9016235) in 14.7 mL of potassium phosphate buffer (0.1 M, pH

7.4). 45 µL of this A+B solution was added to each well of all the 96-well storage plates and

mixed briefly with pipette. The plates were sealed, and all plates except the 0 h plate were

incubated at 37 ºC, with shaking at 60 rpm. 0.5 h, 1 h, 2 h, and 4 h time points were taken. At

each time point, 450 µL of pre-cooled internal standard was added to quench the reaction. The

quenched plate was then centrifuged (model 5810R, Eppendorf, Westbury, NY) at 4000 rpm for

15 min. 150 µL of supernatant was transferred to a 96-well plate and analyzed by UPLC-MS.

The compounds and internal standard were detected by SIR. The log peak area ratio (compound

peak area / internal standard peak area) was plotted vs. time (h), and the slope was determined to

calculate the elimination rate constant [k = (-2.303) * slope]. The half-life (h) was calculated as t

1/2 = 0.693 / k. Intrinsic clearance was calculated as CLint = (0.693 / (t1/2) * (1 / microsomal

concentration in the reaction solution) * (45 mg microsome / g liver) * (g liver / kg b.w.), where

microsomal concentration in the reaction solution is 0.5 mg/mL, and g liver / kg b.w. of CD-1

female mice and human are 52 and 20, respectively.

Caco-2 and MDR1-MDCKII permeability assay. High throughput Caco-2 and MDR1-

MDCKII permeability was performed in the Transwell® 0.4 µm polycarbonate membrane 96-

well system with modified methods.1, 2

Caco-2 and MDR1-MDCKII cells were maintained at 37

°C in a humidified incubator with an atmosphere of 5% CO2. The cells were cultured in 75 cm2

flasks with Dulbecco’s Modified Eagle’s Medium (DMEM) containing 10% fetal bovine serum

(FBS), 1% non-essential amino acids (NEAA), 100 units/ml of penicillin, and 100 µg/ml of

streptomycin. The Caco-2 and MDR1-MDCKII cells were seeded onto inserts at a density of

2×104 and 1×10

4 cells/insert separately. The medium in the wells was exchanged each other day,

and the trans epithelial electrical resistance (TEER) value was measured using an epithelial volt-

ohm meter (Millipore, Billerica, Massachusetts). Caco2 cells were grown for 7 days and MDR1-

MDCKII cells were grown for 4 days to reach consistent TEER values (typically 2000 ohms

greater than initial value when cells are first seeded into transwells), indicating that the cells had

formed a confluent polarized monolayer.

For transport experiments, each cultured monolayer on the 96-well plate was washed twice with

a transport buffer (HBSS/25 mM HEPES, pH 7.4). The permeability assay was initiated by the

addition of each compound solution (10 µmol/L) into inserts (apical side, A) or receivers

(basolateral side, B). The Caco-2 cell monolayers were incubated for 2 h at 37 °C and the

MDR1-MDCKII cell monolayers were incubated for 1 hour at 37 °C. Fractions were collected

from receivers (if apical to basal permeability) or inserts (if basal to apical permeability), and

concentrations were assessed by UPLC/MS (Waters; Milford, MA). All compounds were tested

in triplicates.

The A→B (or B→A) apparent permeability coefficients (Papp) of each compound were

calculated using the equation, Papp=dQ/dt×1/AC0, where dQ/dt equals the flux of a drug across

the monolayer, A equals the total insert well surface area, and C0 is the initial concentration of

substrate in the donor compartment. The efflux ratio was determined by dividing the Papp in the

Page 5: 2376479 File000001 40983185

S5

B-A direction by the Papp in the A-B direction. An efflux ratio >2 suggested that a given substrate

was actively transported across the membrane.

Maximum tolerated dose (MTD) study in mice. During the acute observation phase after

dosing, no adverse reactions or compound-related side effects were observed based on based on

a functional observational battery. All animals maintained normal feeding behavior and body

weight during the 48 h period following i.p. administration of compound at all doses. No

significant changes to hematological parameters, clinical chemistries, or gross organ anatomy

were observed at the terminal point of the study. However, previous pilot study suggested rapid

neurotic/cardiac driven toxicity at 50 mg/kg, and a plunge of plasma glucose levels were

observed within 30 minutes post injection (data not shown). The blood work of compound 5e

after IP dosing is summarized in Table S6.

PK analysis was conducted on an AB Sciex 6500 coupled to Waters Acquity UPLC

(LC/MS/MS) using positive electrospray ionization multiple reaction monitoring (MRM) mode.

An Acquity BEH C18, 1.7 µM, 2.1*50 mm column with acetonitrile (B) – water (A) gradient

containing 0.1% formic acid as mobile phase. LC conditions were a gradient (98-20% A), cycle

time, 2 min. using an injection volume of 2.5 µL and flow rate of 0.6 mL/min. The calibration

curve was obtained as follows: The calibration was done using the same biological matrices to

ensure the similar recovery. Serial dilution (1:2) of compound stock solution (in DMSO) was

spiked into 99 volumes of blank mouse plasma (final concentration from 13.7 to 3333 nM). 1

volume of spiked plasma was combined with 3 volumes of internal standard (2 µM warfarin in

acetonitrile) to precipitate the mouse plasma proteins. all concentrations in the calibration range

must be no more than 20% deviation. If there were any points with more than 20% deviation on

the high or low end, the calibration range would be truncated. If an outlier occurred in the middle

of the curve, the whole curve would be re-done. The signal: noise of the compound peak at the

LLOQ must be greater than 5. Partial validation is achieved if >75% duplicated calibrations,

>2/3rd of total QCs, >50% QC from each level, meet acceptance interval <20% for LLOQ, 15%

for other levels. The samples are tested on the same or second day and another set of QC ran

immediately after sample analysis.

3-(Pyridin-3-yl)cyclohexan-1-amine (32). A mixture of 31 (0.28 mmol, 1.0 eq.), titanium

(IV) isopropoxide (0.56 mmol, 2.0 eq.), ammonium chloride (0.56 mmol, 2.0 eq.), and

triethylamine (0.56 mmol, 2.0 eq.) were stirred at room temperature in EtOH (2.0 mL, 0.19M) in

a nitrogen atmosphere for 16 h. Sodium borohydride (0.57 mmol, 1.5 eq.) was then added and

the reaciton mixture was allowed to stir at room temperature for an additional 7 h. The reaction

was then quenched with saturated sodium bicarbonated solution (2 mL) and extracted into ethyl

acetate (3 x 5 mL). A thick paste formed and the ethyl acetate was decanted, then washed with

brine, dried organic phase over magnesium sulfate, filtered and concentrated. Purification using

automated flash chromatography (MeOH/DCM) was followed by evaporation giving 32 as a

yellow oil (0.019 g, 29%). TLC Rf 0.4 (10% MeOH/DCM). LC-MS (ESI) m/z: 178 (M + H)+.
