KH-1
KH-1 is a KRASG12D/HDAC2 dual-target inhibitor with Kd values of 11.63 nM and 20.17 nM, respectively. KH-1 induces pancreatic cell apoptosis, cell cycle arrest, and inhibits cell proliferation, invasion and migration, as well as suppresses tumor growth in pancreatic cancer xenograft models. KH-1 can be used for the research of pancreatic cancer.

KH-1 binds specifically to purified KRASG12D protein with high nanomolar affinity (Kd = 11.63 nM via MST, 8.62 nM via ITC); it also binds to purified HDAC2 protein (Kd = 20.17 nM via MST, 17.14 nM via ITC), which represents its primary HDAC target[1].
KH-1 exhibits only extremely low off-target inhibitory activity against 330 tested kinases, with an IC50 value > 10 μM[1].
KH-1 (0.5-12.5 μM; 10 days) potently inhibits the proliferation of human pancreatic cancer Capan-1 (IC50 = 0.49 μM) and PANC-1 cells in a dose-dependent manner, but does not suppress the growth of KRASWT, KRASG12C, or non-malignant pancreatic epithelial cells[1].
KH-1 (0.5-12.5 μM; 48 h) potently inhibits the migration and invasion of human pancreatic cancer Capan-1 and PANC-1 cells in a dose-dependent manner[1].
KH-1 (0.5-12.5 μM) induces dose-dependent apoptosis in human pancreatic cancer Capan-1 and PANC-1 cells; the proportion of apoptotic cells increases, and the expressions of activated caspase-3 and activated poly (ADP-ribose) polymerase are up-regulated; it induces dose-dependent G0/G1 phase arrest in human pancreatic cancer Capan-1 and PANC-1 cells, accompanied by the up-regulation of p-cdc2 expression and the down-regulation of cyclin B1 expression[1].

Animal Model:BALB/c nude (female, 6 weeks old, pancreatic cancer Capan-1 cell-derived xenograft model)[1]
-
Dosage:1 mg/kg; 10 mg/kg
-
Administration:i.p.; daily; 28 days
-
Result:Significantly suppressed tumor growth and cut tumor weight by ~50%, outperforming KD2AX, Vorinostat and their combination as well as the 10 mg/kg dosage.
Elevated TUNEL signals and lowered Ki67 expression in tumor tissue to trigger antitumor activity.
Exhibited favorable biosafety without altering mouse body weight, serum liver/kidney markers or inflammatory cytokines, and induced no visceral organ lesions confirmed by HE staining.
