124689-65-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 124689-65-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,6,8 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 124689-65:
(8*1)+(7*2)+(6*4)+(5*6)+(4*8)+(3*9)+(2*6)+(1*5)=152
152 % 10 = 2
So 124689-65-2 is a valid CAS Registry Number.

A versatile chemoenzymatic synthesis for the discovery of potent cryptophycin analogs

Brody, Scott I.,Khatri, Yogan,Pietraszkiewicz, Halina,Schmidt, Jennifer J.,Sherman, David H.,Valeriote, Frederick A.,Zhu, Catherine

, p. 524 - 532 (2020)

The cryptophycins are a family of macrocyclic depsipeptide natural products that display exceptionally potent antiproliferative activity against drug-resistant cancers. Unique challenges facing the synthesis and derivatization of this complex group of molecules motivated us to investigate a chemoenzymatic synthesis designed to access new analogs for biological evaluation. The cryptophycin thioesterase (CrpTE) and the cryptophycin epoxidase (CrpE) are a versatile set of enzymes that catalyze macrocyclization and epoxidation of over 20 natural cryptophycin metabolites. Thus, we envisioned a drug development strategy involving their use as standalone biocatalysts for production of unnatural derivatives. Herein, we developed a scalable synthesis of 12 new unit A-B-C-D linear chain elongation intermediates containing heterocyclic aromatic groups as alternatives to the native unit A benzyl group. N-Acetyl cysteamine activated forms of each intermediate were assessed for conversion to macrocyclic products using wild type CrpTE, which demonstrated the exceptional flexibility of this enzyme. Semipreparative scale reactions were conducted for isolation and structural characterization of new cryptophycins. Each was then evaluated as a substrate for CrpE P450 and its ability to generate the epoxidized products from these substrates that possess altered electronics at the unit A styrenyl double bond position. Finally, biological evaluation of the new cryptophycins revealed a des-β-epoxy analog with low picomolar potency, previously limited to cryptophycins bearing epoxide functionality.

Isolation and structure determination of Cryptophycins 38, 326, and 327 from the terrestrial Cyanobacterium Nostoc sp. GSV 224

Cryptophycin-38 (2), -326 (3), and -327 (4) are three new trace constituents of the terrestrial cyanobacterium Nostoc sp. GSV 224. Cryptophycin-38 is a stereoisomer of cryptophycin-1 (1) and to date is the only naturally occurring analogue that possesses

, p. 6206 - 6216 (2007/10/03)

A convergent synthesis of cryptophycins has been developed in which (5S,6R)-5-hydroxy-6-methyl-8-phenylocta-2(E),7(E)-dienoic acid (A) is coupled with an amino acid segment (B). Two stereo-selective routes to A are described, the first employing allylatio
