Diketopiperazine
WebFeb 13, 2014 · We identified a cytochrome P450, DtpC, that performed pyrroloindole ring formation and concurrent dimerization of a diketopiperazine into a homodimeric substance P receptor-inhibiting alkaloid, (−)-ditryptophenaline. Relaxed substrate specificity of DtpC also allowed the formation of two additional novel homo- and heterodimeric compounds.

Webdiketopiperazine alkaloids and polyketides from the mangrove-derived fungus Penicillium sp. Ruiyun Huo1,2, Jinxin Zhang1,2, Shubin Niu3 and Ling Liu1,2* 2,5-Diketopiperazine is an organic compound with the formula (NHCH2C(O))2. The compound features a six-membered ring containing two amide groups at opposite positions in the ring. It was first compound containing a peptide bond to be characterized by X-ray crystallography in 1938. It is the parent of a large class of 2,5-Diketopiperazines (2,5-DKPs) with the formula (NHCH2(R)C(O))2 (R = H, CH3, etc.). They are ubiquitous peptide in nature. They are often foun…
