TIM-3 inhibitors: a promising strategy for tumor immunotherapy

Abstract

Ma et al. recently reported a systematic screening of small-molecule compounds targeting the FG-CC' cleft of T cell immunoglobulin and mucin-containing molecule 3 (TIM-3). They identified a functional Tim-3 inhibitor, ML-T7, that, as a single agent or in combination with anti-PD-1, demonstrated strong antitumor activity in preclinical mouse tumor models, supporting its potential for further clinical translation.
