PAK Inducer

WRN-IN-26 is an orally active Werner syndrome helicase (WRN) inhibitor with a human K_i value of 58.7 μM and an IC₅₀ value of 0.026 μM. WRN-IN-26 selectively targets the cysteine residues of WRN. WRN-IN-26 induces the expression of p21 protein in MSI-H tumor cells. WRN-IN-26 inhibits the growth of MSI-H tumor cells and exhibits potent in vivo efficacy in MSI-H xenograft tumor models. WRN-IN-26 can be used for the research of microsatellite instability-high (MSI-H) cancers.

Sennoside is an orally active apoptosis inducer and stimulant laxative, found in Senna (Cassia angustifolia). Sennoside induces overexpression of wild-type p53 and p21/WAF as part of pathways mediating colonic epithelial cell apoptosis. Sennoside stimulates colonic peristalsis, reverses net water, sodium, chloride absorption to secretion and enhances potassium and calcium secretion. Sennoside increases paracellular permeability to small molecules, accelerates colon transit and softens fecal pellets. Sennoside can be used for the research of constipation, melanosis coli, and colorectal cancer.
