AM-0902 is a potent, selective antagonist of TRPA1 with IC50s of 71 and 131 nM for rTRPA1 and hTRPA1, respectively. AM-0902 is highly permeable (average Papp=44.5 μcm/s in MDCK cells), an unlikely substrate for P-gp (efflux ratio=1.3 in P-gp overexpressing MDCK cells), and demonstrates good solubility (PBS pH 7.4: 226 μM, SIF: 248 μM). AM-0902 shows good selectivity over other TRP channels, as no activity is observed against human TRPV1 or TRPV4, or rat TRPV1, TRPV3, or TRPM8, at concentrations up to 10 μM. AM-0902 inhibits 45Ca2+ flux upon activation of rat TRPA1 with methylglyoxal with an IC50 of 0.019 μM.

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.

Fadrozole is a potent, selective and nonsteroidal inhibitor of aromatase with an IC50 of 6.4 nM.
PKM2 inhibitor displays PKM2 inhibitory activity with the IC50 value of 2.95 μM. The IC50 value for PKM1 is 4-5-fold higher than that for PKM2.
CA-4948 is a reversible kinase inhibitor that modulates IRAK4 function in both the toll-like receptor (TLR) and interleukin 1 receptor (IL-1R) signaling cascades, and demonstrates pharmacodynamic and antitumor activity in in vitro and in vivo nonclinical models.
ONC212, a fluorinated-ONC201 analogue, is broadly efficacious across most solid tumors and hematological malignancies in the low nanomolar range and has robust anti-leukemic activity.
JPH203, a selective L-type amino acid transporter 1 inhibitor, shows a dramatic inhibition of leucine uptake (IC50=0.06 µM) and cell growth (IC50=4.1 µM) in human colon cancer cells (HT-29), human oral cancer cells (YD-38) and leukemic cells.
