143526-61-8 Usage

General Description

The chemical "(2S,16Z,18E,20S,21S,22R,23R,24R,25S,26R,27S,28E)-12-{[tert-butyl(dimethyl)silyl]oxy}-5,21,23-trihydroxy-27-methoxy-2,4,16,20,22,24,26-heptamethyl-1,6,15-trioxo-1,2-dihydro-6H,13H-2,7-(epoxypentadeca[1,11,13]trienoazeno)[1]benzofuro[4,5-a]phenoxazin-25-yl" is a complex organic compound with a highly intricate molecular structure. It consists of multiple hydroxyl groups, methyl groups, and a tert-butyl(dimethyl)silyl group. The chemical also contains a pentadeca[1,11,13]trienoazeno and a benzofuro[4,5-a]phenoxazin unit, as well as a 2,7-epoxy bond. It is a challenging molecule to synthesize and study due to its elaborate structure and the presence of multiple stereocenters.

Check Digit Verification of cas no

The CAS Registry Mumber 143526-61-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,5,2 and 6 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 143526-61:
(8*1)+(7*4)+(6*3)+(5*5)+(4*2)+(3*6)+(2*6)+(1*1)=118
118 % 10 = 8
So 143526-61-8 is a valid CAS Registry Number.

Highly Efficient Synthesis of a Staphylococcus aureus Targeting Payload to Enable the First Antibody–Antibiotic Conjugate

Linghu, Xin,Segraves, Nathaniel L.,Abramovich, Ifat,Wong, Nicholas,Müller, Barbara,Neubauer, Nadja,Fantasia, Serena,Rieth, Sebastian,Bachmann, Stephan,Jansen, Michael,Sowell, C. Gregory,Askin, David,Koenig, Stefan G.,Gosselin, Francis

A practical synthesis of the complex payload for an anti-Staphylococcus aureus THIOMABTM antibody–antibiotic conjugate (TAC) is described. The route takes advantage of a delicate oxidative condensation, achieved using a semi-continuous flow procedure. It allows for the generation of kilogram quantities of a key intermediate to enable a mild nucleophilic aromatic substitution to the tertiary amine free drug. The linker component is introduced as a benzylic chloride, which allows formation of the quaternary ammonium salt linker-drug. This chemical process surmounts numerous synthetic challenges and navigates deeply colored and unstable compounds to support clinical studies to counter S. aureus bacterial infections.
