Among them, five compounds（4g, 4j-4m） showed potent activating effect on both melanogenesis and tyrosinase in vitro compared with positive control（8-MOP）, the most widely used drugs for vitiligo in clinic. Noticeably, compotmds 4h and 4j, which contain morpholine and piperazine, were recognized as the most effective stimnlator of melanogenesis and tyrosianse in B16 cells separately. These derivatives may serve as lead compounds for further drug discovery for the treatment of vitiligo.展开更多

Coumarins are lactones with 1,2-benzopyrone basic structure, and are widely distributed in the plant kingdom, both in free form, and in glycosylated form. This work reports a literature review, describing the data of 13C NMR from 53 coumarins isolated from the family Moraceae, and data comparison between genera who presented photochemical studies, in order to contribute to the chemotaxonomy of this family.展开更多
