Description:	CID44216842 (Cdc42-IN-1) is a potent Cdc42-selective guanine nucleotide binding lead inhibitor. The EC50s for Cdc42 WT and Cdc42Q61L mutant are 1.0 and 1.2 μM in GTP binding assay, respectively. The EC50s for Cdc42 WT and Cdc42Q61L mutant are 0.3 and 0.5 μM in GDP binding assay, respectively. Use as a molecular probe[1].
Target:	EC50: 1.0 μM (Cdc42 WT, in GTP binding assay) and 1.2 μM (Cdc42Q61L mutant, in GTP binding assay)[1] EC50: 0.3 μM (Cdc42 WT, in GDP binding assay) and 0.5 μM (Cdc42Q61L mutant, in GDP binding assay)[1]
In Vitro:	CID44216842 inhibits GTP binding to both Cdc42 and its mutant in a dose-dependent manner. The inhibition is specific toward Cdc42 with no effects on other GTPases including Rac and Rho in the same family[1].

Cat. No.	Product name	Field of application
DC58063	HG106	HG106 is a potent SLC7A11 inhibitor and enhances ROS generation, ER stress, and ultimately growth arrest specifically in KRAS-mutant lung adenocarcinoma (LUAD).
DC74365	RMC-4998	RMC-4998 (RMC4998) is a tricomplex inhibitor that targets the active state or GTP-bound state of KRAS G12C, selectively inhibits the proliferation of KRASG12C mutant cells with mean IC50 of 0.28 nM.
DC74360	BC-DXI-32982	BC-DXI-32982 is a potent inhibitor of the interaction between DX2 and KRAS4B with a half-maximal inhibitory concentration (IC50) of 0.18 μM, showing little effect on the PRKACA-PRKAR2A interaction.
DC70730	Ras binder 2C07	Ras binder 2C07 is a switch-II binding ligand which binds Ras GDP and GTP states.
DC70578	LY-3537982	LY-3537982 (LY3537982) is a highly selective and potent KRAS-G12C inhibitor, selectively inhibits growth of KRAS G12C mutant cells (IC50=1-60 nM).LY-3537982 does not inhibit growth of KRAS G12S/G13C/G12D mutant cells and WT KRAS cells (CI50>10 uM).LY-3537982 displays high selectivity for proteome-wide cysteine residues was evaluated using competitive chemical proteomics (8866 peptides).LY3537982 inhibits the growth of subcutaneous EL3187 NSCLC PDX tumors in nude mice in a dose dependent manner.LY3537982 demonstrates robust tumor regression in combination with other agents in KRAS G12C in vivo models.LY3537982 is a promising KRAS G12C inhibitor predicted to deliver >90% KRAS G12C target occupancy in the clinic.
DC70535	KAL-21404358	KAL-21404358 (KAL21404358) is a small-molecule, allosteric inhibitor of K-Ras(G12D), binds to K-Ras(G12D) P110 site with KD of 88 uM in MST assay; KAL-21404358 disrupts the K-RasG12D-B-Raf interaction using a NanoBiT split luciferase assay, and to impair the Raf-MEK-ERK and the PI3K-AKT signaling pathways. KAL-21404358 exhibited specificity for K-RasG12D over K-RasWT, H-RasWT, Rap1a, R-Ras and R-Ras2.
DC70512	IODVA1	IODVA1 is a small molecule with cellular inhibitory activity against several transformed cell lines including Ras-driven cells, targets Rac activation and signaling instead of Ras; IODVA1 inhibits ST8814 cell proliferation with GI50 of 1 uM, similar results were observed with MCF7, MDA-MB-231, and T47D cells with estimated GI50s <1 uM. IODVA1 significantly decreases number of colonies of the breast cancer cells in soft agar at 1 and 3 uM. IODVA1 probably does not bind Ras and that its mechanism of action is likely Ras-independent, inhibits lamellipodia and circular dorsal ruffle (CDR) formation in MDA-MB-231 cells and decreases Rac activation. IODVA1 inhibits Rac activation and downstream signaling leading to inhibition of lamellipodia and CDR formation; IODVA1 inhibits cell-substratum and cell-cell interactions, does not target kinases, and reduces tumor burden of solid tumors in vivo.
DC70371	DW0254	DW0254 (DW-0254,DW 0254) is a small molecules capable of inhibiting RAS-related C3 botulinum toxin substrate (RAC) small GTPase activation in ALL cell lines, directly binds to the hydrophobic pocket of PDE6D (Kd=436 nM, ITC), a RAS chaperone protein.DW0254 demonstrated dose-dependent RAC inhibition, arrest of proliferation and induced apoptosis in human leukemic cell lines (RS4;11 IC50=1.5-1.8 uM), also showed promising anti-leukemic activity in RAS-mutated cells (CCRF-CEM NRAS G12D, IC50=3.3-4.2 uM).DW0254 disrupted the interaction between PDE6D and RAS, disturbing RAS subcellular localization.DW0254 demonstrated anti-leukemic activity, decreased tumor progression in a murine xenograft model.
DC70046	MRTX 0902	MRTX0902 is a potent SOS1 inhibitor with an IC50 of 46 nM (WO2021127429A1; Example 12-10).
