Stenoparib Stenoparib, also known as E7449 and 2X-121, is an orally available small molecule inhibitor of the nuclear enzymes poly (ADP-ribose) polymerase (PARP) 1 and 2, with potential antineoplastic activity. Upon administration, E7449 selectively binds to PARP 1 and 2, thereby preventing the repair of damaged DNA via the base excision repair (BER) pathway. This agent enhances the accumulation of single and double strand DNA breaks and promotes genomic instability eventually leading to apoptosis. PARP 1/2 inhibitor E7449 may enhance the cytotoxicity of DNA-damaging agents and of radiotherapy. PARP catalyzes post-translational ADP-ribosylation of nuclear proteins that signal and recruit other proteins to repair damaged DNA. Uses: Designed for use in research and industrial production.

Sterigmatocystin Sterigmatocystin is a xanthone isolated by a number of groups in the 1950s as a mycotoxin produced by several species of Aspergillus associated with food and grain contamination. Sterigmatocystin is structurally related to the aflatoxins and while it is considered to be mutagenic, teratogenic and carcinogenic, it is less widespread and potent than the aflatoxins. Sterigmatocystin in the presence of microsomes covalently binds to DNA. It uncouples oxidative phosphorylation but, unlike the aflatoxins, does not induce mitochondrial swelling or hinder Ca2+-induced swelling of mitochondria. More recently, sterigmatocystin has been shown to. Group: Biochemicals. Grades: Highly Purified. CAS No. 10048-13-2. Pack Sizes: 1mg. US Biological Life Sciences. USBiological 1

Steviol Steviol is a diterpenoiic carboxylic alcohol and is isolated from the herbs of Stevia rebaudiana. It is the aglycon derivative of natural sweetener steviol glycosides and is found to be highly mutagenic compared to Stevioside. It inhibits the proliferation of the gastrointestinal cancer cells and the human osteosarcoma U2OS cell line in a dose- and time-dependent manner. It also inhibits human organic anion transporters (hOATs) in uptake assays using murine cells from the S2 segment of proximal tubules. It is selective for hOAT1 and hOAT3 over hOAT2 and hOAT4. It increases CYP3A29 expression and enhances pancreatic beta-cell function and taste sensation by potentiation of TRPM5 channel activity. It can be used to treat polycystic kidney disease. It can promote proteasome and lysosome-mediated AQP2 degradation and slow cyst growth by reducing AQP2 transcription.
