Additional Information:

Santacruzamate A 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). This compound induces apoptosis and cancer cell death only in combination with other HDAC1 inhibitors (2). It is also a potential therapeutic agent for breast cancer (3), it attenuates the Aβ fragment (Aβ25-35)-induced toxicity in PC12 cells by enhancing ER stress tolerance (4). It ameliorates Alzheimer’s disease-like pathology in mouse models (4).
