Nicotinamide N-methyltransferase (NNMT) is a metabolic enzyme that methylates nicotinamide (NAM) using cofactor S-adenosylmethionine (SAM). NNMT overexpression has been linked to diabetes, obesity, and various cancers. In this work, structure-based rational design led the development of potent selective alkynyl bisubstrate inhibitors NNMT. The reported nicotinamide–SAM conjugate (named NS1) features an alkyne as key element closely mimics linear, 180° transition state geometry found in...
The natural nucleoside (+)-sinefungin, structurally similar to cofactor S-adenosyl-l-methionine, inhibits various SAM-dependent methyltransferases (MTs). Access sinefungin analogues could serve as the basis for rational design of small molecule methyltransferase inhibitors. We developed a route unnatural C9′ epimer that employed diastereoselective Overman rearrangement install key C6′ amino stereocenter. ability late-stage modification is highlighted, opening an avenue discovery new MT
