Kinase modulators represent a very hot topic in drug discovery: 52 protein kinase inhibitors are approved drugs, with several hundred undergoing clinical trials [1]. Only in 2019, the US FDA approved four new small molecule protein kinase antagonists. Moreover, over the past 10 years, the number of protein kinase inhibitor chemotypes has dramatically expanded [2].
Life Chemicals offers its proprietary Kinase Screening Library (KSL) built by the front-end industry standards [3,4]. KSL was designed based on about 1,000 Markush structures and pharmacophore models of known kinase inhibitors derived from ChEMBL and PubChem databases. Our 2D similarity search allowed us to select almost 3,000 drug-like screening compounds of potential inhibitors and activators targeting key kinases in cancer and inflammation from our proprietary HTS Compound Collection. Information on the closest homolog with its highest activity from the ChEMBL and PubChem databases was added to each compound entry (examples in Fig. 1).
KSL aims to provide high-quality hits for drug discovery projects related to kinases and other ATP-binding proteins. The Library contains:
- Inhibitors of protein kinases heavily pursued by industry: ACVRL, ABL, ADK, AKT, ALK, AMPK, Aurora, ATM, AXL, Bcr-ABL, βARK1, Braf, BMX, BRK, BTK, CAMK, CDK, CDC7, CqsS, cFMS, CHK, CK, CNKSR1, cKIT, cMET, CLK, CPK, DAPK, DNA-PK, DYRK, EEFK, EGFR, EPH, erbB, FAK, FLT3, Fyn, GRK, GSK, HK, HPK, HER, JAK, JNK, IGFR, IKK, ILK, IRE, IRAK, ITK, KDR, LCK, luxN, LIMK, LRRK, MAPK, MEK, MELK, MLCK, mTOR, p38α, PAK, PASK, PDPK, PDGF, PIK, PIM, PIP, PGK, PKA, PKC, PFK, PFMRK, PKM2, PLK, PknB, PRKACA, PRMT, RAF, RET, RIPK, ROCK, RTK, SH2, SAPK, SRC, S6K, SKSphK, SPHK, SYK, SGK, TAO, Tie2, TGFB, TK2, TRPM, Trk, TTSP, VEGFR, ZAP-70
