CAY10683 (SantacruzaMate A) Usage And Synthesis

Description

Santacruzamate A (1477949-42-0) is a highly potent and selective inhibitor of HDAC2 isolated from the Panamanian marine cyanobacterium?cf. Symploca?(IC50=0.119 and 434 nM for HDAC2 and HDAC6 respectively).1?Induces apoptosis and cancer cell death only in combination with other HDAC1 inhibitors.2?Potential therapeutic agent for breast cancer.3?Attenuates Aβ fragment (Aβ25-35)-induced toxicity in PC12 cells by enhancing ER stress tolerance.4?Ameliorates Alzheimer’s disease-like pathology in mouse models.4

Uses

Santacruzamate A is a natural product isolated from Panamanian marine cyanobacterium Symploca sp; a histone deacetylases (HDACs) inhibitor; an attractive targeted therapy against breast cancer in women.

Definition

Background

Santacruzamate A is a cytotoxin isolated from the Panamanian marine cyanobacterium cf. Symploca sp., and is a highly selective inhibitor of histone deacetylases, specifically HDAC2 and HDAC6. This small molecule has been shown to induce apoptosis via transcriptional inhibition of HDAC2, resulting in an increase of p21 Waf1/Cip1 and p19INK4d expression when combined with an HDAC1 inhibitor. Santacruzamate A has also demonstrated the ability to attenuate amyloid-β protein fragment-induced toxicity through enhancing endoplasmic reticulum stress tolerance in mice. Additionally, HDAC2 has been recognized as a host immune response to the influenza A virus and several other viruses, making HDAC inhibitors important compounds to study in relation to viral diseases.
