Four new amino acid derivatives, herdmanines A–D (1–4), were isolated from the marine ascidian Herdmania momus. Herdmanines A–C contain the unusual d-form of arginine. Compounds 3 and 4 had a moderate suppressive effect on the production of NO, with IC50 values of 96 and 9 μM, respectively. These compounds were found to inhibit the mRNA expression of iNOS. The inhibitory activities on the production
四个新的氨基酸衍生物,herdmanines A-d(1 - 4),是从海洋海鞘分离Herdmania MOMUS。Herdmanines A–C含有不常见的d-精氨酸形式。化合物3和4对NO的产生具有中等程度的抑制作用,IC 50值分别为96和9μM。发现这些化合物抑制iNOS的mRNA表达。评价了对促炎细胞因子例如TNF-α,IL-1β和IL-6的产生和mRNA表达的抑制活性。
