Acid mediated ring closing metathesis: A powerful synthetic tool enabling the synthesis of clinical stage kinase inhibitors

, p. 142 - 145 (2015/04/27)
The powerful olefin metathesis reaction was employed for the construction of late-phase clinical agents SB1317 and SB1518. In both cases RCM seems to proceed only in the presence of an acid and to predominantly furnish trans isomers. In case of SB1518 it proceeded in the presence of acid HCl, while for SB1317, it mainly proceeds in the presence of TFA (trifluroacetic acid).

Herein, we describe the design, synthesis, and SAR of a series of unique small molecule macrocycles that show spectrum selective kinase inhibition of CDKs, JAK2, and FLT3. The most promising leads were assessed in vitro for their inhibition of cancer cell proliferation, solubility, CYP450 inhibition, and microsomal stability. This screening cascade revealed 26h as a preferred compound with target IC50 of 13, 73, and 56 nM for CDK2, JAK2 and FLT3, respectively. Pharmacokinetic (PK) studies of 26h in preclinical species showed good oral exposures. Oral efficacy was observed in colon (HCT-116) and lymphoma (Ramos) xenograft studies, in line with the observed PK/PD correlation. 26h (SB1317/TG02) was progressed into development in 2010 and is currently undergoing phase 1 clinical trials in advanced leukemias and multiple myeloma.
