cusp

Cuspidoside is a cardiac glycoside.

The Survival of Motor Neurons (SMN) protein participates in RNA splicing. Decreases in SMN, typically a consequence of defects in the smn1 gene, result in the death of motor neurons and lead to the neurodegenerative disease, spinal muscular atrophy (SMA). Cuspin-1 is a small molecule upregulator of SMN that has been shown in vitro to increase levels of SMN in SMA patient fibroblasts by 50% at 18 μM. Its mechanism of action is thought to involve increased phosphorylation of ERK to initiate Ras-Raf-MEK signaling, which results in an increased rate of SMN translation.

Monascuspiloin (Monascinol), a compound extracted from rice fermented with Rhodobacter sphaeroides, exhibits antiandrogenic and antitumor activity and inhibits the proliferation of PC-3 and LNCaP.Monascuspiloin improves lipid metabolism and hepatic function in over-alcohol-addicted mice by decreasing hepatic MDA levels and increasing hepatic CAT, SOD and GSH levels.Monascuspiloin has been shown to improve lipid metabolism and hepatic function in over-alcoholized mice. Monascuspiloin regulates the transcription and protein expression of genes related to hepatic lipid metabolism and oxidative stress, and can be used to study alcohol-induced liver injury.

Cuspidiol shows cytotoxicity against Jurkat T cell clone E6.1 at 7.3 ug/mL.
