The Bcl-2 family of proteins plays a major role in the regulation of apoptosis, or programmed cell death. Overexpression of the anti-apoptotic members of this family (Bcl-2, Bcl-x(L), and Mcl-1) can render cancer cells resistant to chemotherapeutic agents and therefore these proteins are important targets for the development of new anti-cancer agents. Here we describe the discovery of a potent, highly selective, Bcl-2 inhibitor using SAR by NMR and structure-based drug design which could serve as a starting point for the development of a Bcl-2 selective anti-cancer agent. Such an agent would potentially overcome the Bcl-x(L) mediated thrombocytopenia observed with ABT-263.

Metabolites derived from the intestinal microbiota, including bile acids (BA), extensively modulate vertebrate physiology, including development, metabolism, immune responses and cognitive function. However, to what extent host responses balance the physiological effects of microbiota-derived metabolites remains unclear. Here, using untargeted metabolomics of mouse tissues, we identified a family of BA-methylcysteamine (BA-MCY) conjugates that are abundant in the intestine and dependent on vanin 1 (VNN1), a pantetheinase highly expressed in intestinal tissues.

Daphnane diterpenoids occurring in plants of the Thymelaeaceae are the focus of natural product drug discovery because of the wide range of their therapeutically biological activities. Considering the limited occurrence in some plants of the Thymelaeaceae, it is imperative to design a strategy for the target isolation of daphnane diterpenoids. In this study, a strategy was developed to filter the data using MZmine, generate the molecular network using the Global Natural Product Social Molecular Network Platform (GNPS), and determine the retention time of target compounds using MS-DIAL.

Tropomyosin receptor kinase (TRK) has emerged as a promising therapeutic target in cancers driven by NTRK gene fusions. Herein, we report a highly potent TRK inhibitor, C11, developed using bioisosteric replacement and computer-aided drug design (CADD) strategies. Compound C11 demonstrated significant antiproliferative effects against TRK-dependent cell lines (Km-12), and exhibited a dose-dependent inhibition of both colony formation and cell migration.

Targeted covalent inhibitors (TCIs) play an essential role in the fields of kinase research and drug discovery. Most existing TCIs are however cysteine- or lysine-reactive, thus severely limiting their potential applications. New types of TCIs capable of covalently targeting other nucleophilic amino acids that are readily available in proteins are urgently needed.

Chronic muscle fatigue is a condition characterized by debilitating muscle weakness and pain. Based on our recent finding to study the potential effect of mTOR on ATG13 inactivation in chronic muscle fatigue, we report that biweekly oral administration with MHY1485, a potent inducer of mTOR, develops chronic illness in mice resulting in severe muscle weakness. As a mechanism, we observed that MHY1485 feeding impaired ATG13-dependent autophagy, caused the infiltration of inflammatory M1 macrophages (Mφ), upregulated IL6 and RANTES by STAT3 activation, and augmented demyelination in muscle-serving nerve fibers.
