Silver(I) promotes the highly chemoselective N-amidation of tertiary amines under catalytic conditions to form aminimides by nitrene transfer from PhI═NTs. Remarkably, this transformation proceeds in a selective manner in the presence of olefins and other functional groups without formation of the commonly observed aziridines or C-H insertion products. The methodology can be applied not only to rather
potential target for the discovery of chemosensitizers and anticancer drugs. Amentoflavone (AMF) is reported to be a selective PARP-1 inhibitor. Here, structural modifications and trimming of AMF have led to a series of AMF derivatives (9a–h) and apigenin–piperazine/piperidine hybrids (14a–p, 15a–p, 17a–h, and 19a–f), respectively. Among these compounds, 15l exhibited a potent PARP-1 inhibitory effect

A series of novel 1,4-disubstitutedpiperidine/piperazine derivatives were designed, synthesized and evaluated for their in vitro activities against HIV-1 Bal (R5) infection in CEMX174 5.25M7 cells. A majority of these compounds showed potent anti-HIV-1 activities with IC at nanomolar levels. -(4-Fluoro-benzyl)piperazine analog hydrochloride exhibited potency against HIV-1 activity similar to that of

This disclosure features chemical entities (e.g., a compound or a pharmaceutically acceptable salt, and/or hydrate, and/or cocrystal, and/or drug combination of the compound) that inhibit (e.g., antagonize) Stimulator of Interferon Genes (STING). Said chemical entities are useful, e.g., for treating a condition, disease or disorder in which increased (e.g., excessive) STING activation (e.g., STING signaling) contributes to the pathology and/or symptoms and/or progression of the condition, disease or disorder (e.g., cancer) in a subject (e.g., a human). This disclosure also features compositions containing the same as well as methods of using and making the same.
