New Water-Soluble Duocarmycin Derivatives: Synthesis and Antitumor Activity of A-Ring Pyrrole Compounds Bearing β-Heteroarylacryloyl Groups
摘要:
A series of A-ring pyrrole compounds of duocarmycin bearing 4'-methoxy-beta-heteroarylacryloyl groups were synthesized and evaluated for in vitro anticellular activity against HeLa S-3 cells and in vivo antitumor activity against murine sarcoma 180 in mice. Most of the Li 4'-methoxy-beta-heteroarylacrylates displayed in vitro anticellular activity equivalent to that of 4'-methoxycinnamates, Among the 8-O-[(N-methylpiperazinyl)carbonyl] derivatives of 4'-methoxy-beta-heteroarylacrylates, compound 15b having a (4-methoxy-3,5-pyrimidinyl)acryloyl as segment-B (Seg-B) showed remarkably potent in vivo antitumor activity and low peripheral blood toxicity compared with the A-ring pyrrole derivatives having the trimethoxyindole skeleton in Seg-B, which were equal to 8-O-[(N-methylpiperazinyl)carbonyl] derivatives of 4'-methoxycinnamates. Moreover, these 8-O-[(N-methylpiperazinyl)carbonyl] derivatives of 4'-methoxy-beta-heteroarylacrylates had high aqueous solubility.

The present disclosure relates to bifunctional compounds, which find utility as modulators of SMARCA2 or BRM (target protein). In particular, the present disclosure is directed to bifunctional compounds, which contain on one end a ligand that binds to the Von Hippel-Lindau E3 ubiquitin ligase, and on the other end a moiety which binds the target protein, such that the target protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of target protein. The present disclosure exhibits a broad range of pharmacological activities associated with degradation/inhibition of target protein. Diseases or disorders that result from aggregation or accumulation of the target protein are treated or prevented with compounds and compositions of the present disclosure.
