Psammaplin A is an antibiotic, anti-tumor, DNA methyltransferase inhibitor.
Psammaplin A is an antibiotic, anti-tumor, DNA methyltransferase inhibitor. It is a bromotyrosine-derived, symmetrical conjugate of cystamine, which was first isolated from the Psammaplinaplysilla sponge. Psammaplin A impedes angiogenesis as well as bacterial and tumor cell growth. Psammaplin A 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.

The symmetrical disulfide psammaplin A from the marine sponge Pseudoceratina sp. was synthesized and structurally altered by replacement of one of the α-(hydroxyimino)acyl units by a fluorescent 4-coumarinacetyl moiety. Thus, the first fluorescent analogs of psammaplin A were obtained. Structural

Activated chemical defense, i.e., the rapid conversion of precursor molecules to defensive compounds following tissue damage, has been well documented for terrestrial and marine plants; but evidence for its presence in sessile marine invertebrates remains scarce. We observed a wound-activated

A collection of analogues of the dimeric natural product psammaplin A that differ in the substitution on the (halo)tyrosine aryl ring, the oxime and the diamine connection has been synthesized. The effects on cell cycle, induction of differentiation and apoptosis

Histone modifications and DNA methylation are two major factors in epigenetic phenomenon. Unlike the histone deacetylase inhibitors, which are known to exert radiosensitizing effects, there have only been a few studies thus far concerning the role of DNA methyltransferase (DNMT)

Histone deacetylase (HDAC) has been highlighted as one of key players in tumorigenesis and angiogenesis. Recently, several derivatives of psammaplin (Psams) from a marine sponge have been known to inhibit the HDAC activity, but the molecular mechanism for the inhibition
