Description
Gedunin is a natural inhibitor of the heat shock protein (Hsp90; Item Nos. 22734 | 22735) co-chaperone p23 that also inhibits Hsp90 expression in human teratocarcinomal NTERA-2 cells in vitro at 5 μg/ml. This tetranortriterpenoid, which is isolated from A. indica, binds to and blocks the chaperone activity of p23 to induce apoptosis in HeLa-PRB cells in vitro at a concentration of 20 μM. Gedunin inhibits breast cancer cell proliferation in vitro, with IC50 values of 8.84 and 3.22 μM in MCF-7 and SKBr-3 cells, respectively, and inhibits the growth of PANC-1 pancreatic cancer cells (IC50 = 25 μM) by targeting the sonic hedgehog pathway to induce apoptosis. It also exerts anti-inflammatory effects in vivo. In a mouse model of articular inflammation induced by zymosan , gedunin (0.05-0.5 mg/kg, i.p.) reduces edema formation and the production of inflammatory cytokines. Gedunin (0.5 mg/kg) also inhibits the pleural accumulation of eosinophils and activated T lymphocytes in an ovalbumin-sensitized mouse model of allergic inflammation when administered prior to ovalbumin rechallenge. It also targets the lipopolysaccharide binding site and thus blocks Toll-like receptor 4 (TLR4) signaling in macrophages in vitro at a concentration of 10 μM.
Uses
Gedunin is a naturally occurring Hsp90 inhibitor. In vitro, Gedunin induces Hsp90-dependent client protein degradation and displays antiproliferative activity (IC50 values are 3.22, 8.84 and 16.8 μM in SKBr3, MCF-7 and CaCo-2 cancer cell lines respectively). Gedunin exhibits antimalarial activity against P. falciparum (IC50 values are 0.14 and 3.1 μM in parasite development and [3H]-hypoxanthine uptake assays respectively).

Check Digit Verification of cas no
The CAS Registry Mumber 2753-30-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,5 and 3 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 2753-30:
(6*2)+(5*7)+(4*5)+(3*3)+(2*3)+(1*0)=82
82 % 10 = 2
So 2753-30-2 is a valid CAS Registry Number.

Biocatalysis: Fungi mediated novel and selective 12β- or 17β-hydroxylation on the basic limonoid skeleton

Basic limonoids carrying a 4,4,8-trimethyl-17-furanylsteroid skeleton are a class of triterpenoids and well-known for their insecticidal as well as a vast array of pharmacological activities. Rare and synthetically challenging 12β- and 17β-hydroxylation was achieved on the basic limonoid skeleton to produce a novel series of hydroxylated limonoids using fungi-mediated biocatalysis. The fungal system belonging to the genera of Mucor efficiently converted azadiradione, epoxyazadiradione, gedunin and their derivatives into corresponding 12β- and/or 17β-hydroxy derivatives. The position and stereochemistry of hydroxylation was determined by rigorous spectroscopic and crystallographic studies. This fungi-mediated stereo- and regio-selective hydroxylation process was highly efficient and mild enough to sustain chemically sensitive functional groups around the basic limonoid skeleton. Modifications of specific functional groups and variation in biocatalyst were shown to bring selectivity among 12β- or 17β-hydroxylation.
