Abstract
Description
HETEROCYCLIC COMPOUNDS, COMPOSITIONS THEREOF, AND METHODS OF TREATMENT THEREWITHFIELD
[0001] Provided herein are heterocyclic compounds that inhibit KRAS activity, as well as their pharmaceutical compositions and methods of use.BACKGROUND
[0002] Ras is a family of proteins which are associated with cell membrane through their C-terminal membrane targeting region and well known as the molecular switch in intracellular signaling network (Cox AD, Der CJ. Ras history: The saga continues. Small GTPases. 2010; 1 (1) : 2-27) . Ras proteins bind with either GTP or GDP and switch between “on” and “off” states. By switching to active state, Ras protein can interact with different downstream proteins and activate related signaling pathways (Berndt N, Hamilton AD, Sebti SM. Targeting protein prenylation for cancer therapy. Nat Rev Cancer. 2011; 11 (11) : 775-791) . HRas, NRas and KRas are the most well studied proteins in Ras family since these proteins are the most common oncogenes in human cancers (O'Bryan JP. Pharmacological targeting of RAS: Recent success with direct inhibitors. Pharmacol Res. 2019; 139: 503-511) .
[0003] KRas is one of the most frequently mutated genes in human cancers.
[0004] Among different cancers, pancreatic cancer is considered as the most KRas-addicted cancer type. KRas mutation is found in 94.1%of pancreatic ductal adenocarcinoma (PDAC) . G12D (41%) mutation of KRas is the most predominant mutations in all the KRas mutated PDAC (Waters AM, Der CJ. KRAS: The Critical Driver and Therapeutic Target for Pancreatic Cancer. Cold Spring Harb Perspect Med. 2018; 8 (9) : a031435) .
[0005] Thus, KRas G12D mutation is a highly attractive target for pancreatic cancer and other cancers with this mutation. As such, small-molecule therapeutic agents that are capable to selectively bind with KRas G12D and inhibit its function would be very useful.

GST-tagged GDP-loaded WT KRAS (amino acids 1-188) and GST-tagged GDP-loaded KRAS G12D (amin acids 1-188) were expressed in E. coli and purified in house. All protein and reaction solutions were prepared in assay buffer containing 50 mM HEPES pH7.5, 50mM NaCl, 1 mM MgCl2, 1 mM TCEP, 0.01 %BSA, and 0.008%Brij-35. Purified WT KRAS (3 nM final concentration) or KRAS G12D protein (0.5 nM final concentration) was incubated with a 3-fold serially diluted compound in the assay plate (384 well microplate, black, Corning) . Plates are incubated at 24℃ for 1 hr. Following the incubation, biotinylated probe 1 (60 nM final assay concentration) for WT KRAS and biotinylated probe 2 (4 nM final assay concentration) for KRAS G12D was added to the assay plate, respectively. After 1 hr incubation at 24℃, Mab Anti-GST-Tb cryptate (Cisbio) and Streptavidin-XL665 (Cisbio) were added and further incubated at 24℃ for another 1 hr. The TR-FRET signals (ex337nm, em665nm / 620nm) were read on BMG PHERAstar FSX instrument. The inhibition percentage of KRAS protein binding with biotinylated probe in presence of increasing concentrations of compounds was calculated based on the ratio of fluorescence at 665 nm to that at 620 nm. The IC50 value of each compound was calculated from fitting the data to the four-parameter logistic model by Dotmatics.

Test compounds was added to incubation system at final concentration of 1 μM and incubated at 37℃. The incubation was initiated by the addition of NADPH into the system. Aliquots of 20 μL were taken from the incubation system at 0, 15, 30, 45 and 60 min after the initiation of incubation. The reaction solutions were stopped by the addition of cold acetonitrile with analytical IS. Samples were centrifuged at 4000 rpm for 5 minutes and were then analyzed on LC-MS / MS.
[0594] Peak areas of samples from various timepoints were determined from extracted ion chromatograms; and were then plotted to calculate metabolic stability. The slope value, k, was determined by linear regression of the natural logarithm of the remaining percentage of the parent drug vs. incubation time curve. The in vitro half-life (in vitro t1 / 2) was determined from the slope value: in vitro t1 / 2=- (0.693 / k)
[0595] Conversion of the in vitro t1 / 2 (in min) into the in vitro intrinsic clearance (in vitro CLint, in μL / min / mg proteins) was done using the following equation (mean of duplicate determinations) :
[0596] The control compound (verapamil) was included in the assay to ensure the data consistency. The negative control (identical experimental set-up but no NADPH in the incubation system) was used to exclude the misleading factor that resulted from instability of chemical itself.

The incubation plate was pre-warmed at 37℃ for 5 min in water bath before the reactions are started by the addition of 20 -L of 10 mM NADPH solution. The reaction was carried out in the 37℃-water bath.
[0599] At the predetermined time points, the reaction was stopped by adding 300 μL of quenching solution (acetonitrile with internal standards) to each well. The sample plate was vortexed for 1 min and centrifuged at 3000 g for 10 min. 100 μL of the supernatant was transferred to a new 96-well plate then mixed with 100 μL water for analysis by LC-MS / MS followed by data processing (i.e., percent inhibition at 10 uM or IC50 determination) .

[0604] To determine the rate of drug transport in the apical to basolateral direction. 125 μL of test compound working solution were added to the Transwell insert (apical compartment) , and transferred 50 μL sample (D0 sample) immediately from the apical compartment to a new 96-well plate. To determine the rate of drug transport in the basolateral to apical direction. 285 μL of working solution of compounds are added to the receiver plate wells (basolateral compartment) , and transfer 50 μL sample (D0 sample) immediately from the basolateral compartment to a new 96-well plate. The plates are incubated at 37 ℃for 2 hours. At the end of the transport period, transfer 50 μL directly from the apical and basolateral wells and transfer to a new plate. Then add 200 μL of cold acetonitrile containing internal standards (IS: 2 μM ketoprofen, 200 nM labetalol, 200 nM caffeine and 100 nM alprazolam) into the plate. Vortex for 5 minutes. Samples are centrifuged at 3, 220 g for 20 minutes. Aliquot of 100 μL of the supernatant is diluted by 100 μL ultra-pure H2O, and the mixture is used for LC / MS / MS analysis. All incubations are performed in duplicate. The apparent permeability (Papp) , in units of centimeter per second, can be calculated for MDCKII-MDR1 drug transport assays using the following equation:
