Cyclo-L-Trp-L-Trp

Research use only, not for human use.

Cyclo-L-Trp-L-Trp is a broad-spectrum antifungal. It also induces a high degree of acetylation of histones.

Cyclo-L-Trp-L-Trp is a broad-spectrum antifungal. It also induces a high degree of acetylation of histones.(In Vitro):Two novel cyclic hexapeptides designated actinosynneptides A (1) and B (2), together with three tryptophan containing diketopiperazines, namely cyclo(L-Trp-L-Trp) (3), cyclo(L-Trp-N-MeL-Trp) (4), and cyclo(N-MeL-Trp-N-MeL-Trp) (5), were isolated from the culture of the genetically engineered strain HGF052::asm18 derived from Actinosynnema pretiosum ATCC31565. Their structures were elucidated on the basis of spectroscopic analyses and single-crystal X-ray diffractions. Compound 1 is the first example of 3-amino-6-hydroxy-2-piperidone-containing cyclic peptides, and 1 and 2 showed moderate cytotoxic activities against HeLa and PC3 cell lines.

Cyclo(L-Trp-L-Trp) can inhibit A. baumannii (MICs=12.5-25 μg/mL), as well as Candida albicans, Bacillus subtilis, Micrococcus luteus, Saccharomyces cerevisiae, Aspergillus niger, Staphylococcus aureus (MICs=12.5-50 μg/mL).
