Preclinical and first-in-human of Purinostat Mesylate, a novel selective HDAC I/IIb inhibitor, in relapsed or refractory multiple myeloma and lymphoma [scRNA-seq]

ABSTRACT: Purinostat Mesylate (PM), a highly selective HDAC I/IIb inhibitor, exhibits excellent antitumor activity in multiple MM and lymphoma cell lines and multiple mouse models, outperforming the pan-HDAC inhibitor panobinostat or first-line/second-line multi-drug combinations. Different from panobinostat, bulk RNA-seq analysis results revealed that PM targeted essential tumor survival factors, and triggered inflammation and interferon responses. ScRNA-seq of 5TMM models further indicated that PM enhanced antitumor immunity by boosting monocyte- and T cell-mediated immune responses.
