17187-82-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 17187-82-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,1,8 and 7 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 17187-82:
(7*1)+(6*7)+(5*1)+(4*8)+(3*7)+(2*8)+(1*2)=125
125 % 10 = 5
So 17187-82-5 is a valid CAS Registry Number.

Affinity-Driven Covalent Modulator of the Glyceraldehyde-3-Phosphate Dehydrogenase (GAPDH) Cascade

Chern, Jeffy,Lu, Chun-Ping,Fang, Zhanxiong,Chang, Ching-Ming,Hua, Kuo-Feng,Chen, Yi-Ting,Ng, Cheng Yang,Chen, Yi-Lin Sophia,Lam, Yulin,Wu, Shih-Hsiung

Traditional medicines provide a fertile ground to explore potent lead compounds, yet their transformation into modern drugs is fraught with challenges in deciphering the target that is mechanistically valid for its biological activity. Herein we reveal that (Z)-(+)-isochaihulactone (1) exhibited significant inhibition against multiple-drug-resistant (MDR) cancer cell lines and mice xenografts. NMR spectroscopy showed that 1 resisted an off-target thiolate, thus indicating that 1 was a target covalent inhibitor (TCI). By identifying the pharmacophore of 1 (α,β-unsaturated moiety), a probe derived from 1 was designed and synthesized for TCI-oriented activity-based proteome profiling. By MS/MS and computer-guided molecular biology approaches, an affinity-driven Michael addition of the noncatalytic C247 residue of GAPDH was found to control the “ON/OFF” switch of apoptosis through non-canonically nuclear GAPDH translocation, which bypasses the common apoptosis-resistant route of MDR cancers.

Diastereoselective synthesis of β-piperonyl-γ-butyrolactones from Morita-Baylis-Hillman adducts. highly efficient synthesis of (±)-yatein, (±)-podorhizol and (±)-epi-podorhizol

Trazzi, Giordano,Andre?, Marcelo Fabiano,Coelho, Fernando

Starting from a Morita-Baylis-Hillman adduct we describe a simple and very efficient method for the diastereoselective preparation of hydroxylated β-piperonyl-γ-butyrolactones. To exemplify the efficiency of this approach we also describe a highly efficie

LIGNANES.10. PREPARATION DES (R)-(+) ET (S)-(-)-β-PIPERONYL ET β-VERATRYL-γ-BUTYROLACTONES ET LEUR UTILISATION DANS LA SYNTHESE TOTALE DE LIGNANES OPTIQUEMENT ACTIFS

Brown, Eric,Daugan, Alain

, p. 141 - 154 (2007/10/02)

A simple and efficient route leading to optically active β-benzyl-γ-butyrolactones is described.Thus, the methyl (R,S)-α-benzylhemisuccinate resulting from a Stobbe condensation with an appropriate aromatic aldehyde, followed by catalytic hydrogenation of the intermediate α-benzylidene hemisuccinic ester, was resolved by means of a chiral base (ephedrine or α-methyl benzylamine).Reduction of each enantiomer, using calcium borohydride, then led to the corresponding optically active β-benzyl-γ-butyrolactone.In this way, the following two lactones were obtained in both (R)-(+) and (S)-(-) enantiomeric forms, β-piperonyl- and β-veratryl-γ-butyrolactones 1 and 2 respectively.These lactones were used as key-intermediates for the syntheses of 17 optically active lignans and lignoids, such as (-)-dimethylmatairesinol (-)-23, (-)-kusunokinin (-)-26 and (+)-dimethylisolariciresinol (+)-35.
