compound introduction
帕马普林 A是一种抗生素抗肿瘤DNA甲基转移酶（Dnmt）抑制剂。它是溴酪氨酸衍生的胱胺对称共轭物，首先从Psammaplinaplysilla海绵中分离出来。阻碍血管生成以及细菌和肿瘤细胞的生长。抑制原核和真核系统中几种关键酶的活性，包括那些参与基因表达的表观遗传控制，DNA复制，血管生成和微生物排毒的酶。 Psammaplin A is an antibiotic, anti-tumor, DNA methyltransferase (Dnmt) inhibitor. It is a bromotyrosine-derived, symmetrical conjugate of cystamine, which was first isolated from the Psammaplinaplysilla sponge. Impedes angiogenesis as well as bacterial and tumor cell growth. Inhibits the activities of several key enzymes in prokaryotic and eukaryotic systems including those involved in epigenetic control of gene expression, DNA replication, angiogensis, and microbial detoxification.
