1-Alaninechlamydocin is a cyclic tetrapeptide metabolite containing a single β-amino acid, which was isolated from a Tolypocladium sp. from the Great Lakes. It has anti-tumor activity due to the inhibition of histone deacetylase (HDAC).
1-Alaninechlamydocin is soluble in ethanol, methanol, DMF and DMSO.
|Mechanism of Action||1-Alaninechlamydocin exhibits potent antitumor activity and acts by inhibiting histone deacetylase.|
|Eukaryotic Cell Culture Applications||
1-Alaninechlamydocin reduces proliferation of MIA PaCa-2, PANC-1, and hTERT-HPNE cells (GI50s = 5.3, 14, and 2.0 nM, respectively).
1-Alaninechlamydocin showed antiproliferative/cytotoxic activity in human pancreatic cancer cell line (MIA PaCa-2) at low-nanomolar concentrations. It also induced G2/M cell cycle arrest and apoptosis. Similar to other cyclic epoxytetrapeptides, its inhibitory effect is proposed to be via inhibition of HDAC activity (Du et al, 2014).
