Ecteinascidins is a family of tetrahydroisoquinoline alkaloids with wide range of antitumor and antimicrobial activities. Ecteinascidin-Analog-1 is a useful intermediate for chemical sythesis of Ecteinascidin analogues.
Piscidinol A is toxic against the 4T1 and HEp2 cancer cell lines, the IC50 of 8.0 ± 0.03 and 8.4 ± 0.01 uM, respectively. It can inhibit NO production in mouse peritoneal macrophages with inhibitory ratios ranging from 39.8±7.7 to 68.2±4.5%.
Viscidulin II can be potential therapeutic agents against P. acnes-induced skin inflammation, it can significantly suppress P. acnes-induced IL-8 and IL-1β production in THP-1 cells, concomitant intradermal injection of viscidulin II with P. acnes can effectively attenuate P. acnes-induced ear swelling, and decrease the production of IL-6 and tumor necrosis factor-α in ear homogenates.
Cimicifugic acid D (2-Caffeoylpiscidic acid) 是一种苄基酒石酸酯,能够诱导预收缩的大鼠主动脉条血管扩张,并启动内皮依赖性舒张机制。在Norepinephrine引起的大鼠主动脉条收缩过程中,Cimicifugic acid D 通过抑制受体操纵的Ca2+通道(ROC)的胞外Ca2+内流发挥作用,而不影响电压依赖性Ca2+通道(VDC)或K+诱导的收缩。
