Description
2-Chloro-N-[4-chloro-3-(2-pyridinyl)phenyl]-4-(methylsulfonyl)benzamide, also known as Vismodegib or Erivedge, is a benzamide compound that has been specifically designed to target and inhibit the Hedgehog (Hh) signaling pathway. This white solid compound has demonstrated potent inhibitory effects on the Hh pathway, making it a valuable pharmaceutical agent for the treatment of various types of human cancers.
Uses
Used in Oncology:
2-Chloro-N-[4-chloro-3-(2-pyridinyl)phenyl]-4-(methylsulfonyl)benzamide is used as a potent Hedgehog inhibitor for the treatment and prevention of many types of human cancers. By inhibiting the Hh signaling pathway, this compound can effectively reduce the downstream production of proliferation factors, thereby suppressing tumor growth and progression.
Used in the Treatment of Basal Cell Carcinoma:
In January 2012, the US FDA approved vismodegib (Erivedge) for the treatment of adults with metastatic basal cell carcinoma (BCC) or locally advanced BCC that has recurred following surgery or for those who are not candidates for surgery or radiation. As an antagonist of SMO, vismodegib inhibits the activation of Hedgehog target genes, resulting in decreased tumor growth and progression.
Used in Drug Synthesis:
A synthesis of vismodegib starting from 2-chloro-5-nitro aniline and employing a Negishi coupling with 2-pyridyl zinc iodide as a key step has been reported. This synthesis process highlights the potential of 2-Chloro-N-[4-chloro-3-(2-pyridinyl)phenyl]-4-(methylsulfonyl)benzamide as a key intermediate in the development of novel therapeutic agents targeting the Hedgehog signaling pathway.
Originator
Curis/Genentech (United States)
Clinical Use
Antineoplastic agent: Treatment of basal cell carcinoma which is inappropriate for surgery or radiotherapy
Synthesis
The synthesis began with selective iodination of commercial carboxylic acid 179, affording
trisubstituted arene 180 in 73% yield. A Curtius reaction then converted 180 to carbamate 181 in 84%
52
yield, and this was followed by a palladium(0)-catalyzed borylation of 181 which furnished Suzuki
coupling partner 182 in 91% yield. Pinacol borane 182 was exposed to commercial 2-bromopyridine
under conventional cross-coupling conditions to furnish biaryl 183, which underwent Boc-deprotection
in quantitative conversion to generate 184. Amide bond formation with acid chloride 185 (readily
available from the corresponding commercial acid) produced vismodegib (XXVIII) in 99% yield.
Drug interactions
Potentially hazardous interactions with other drugs
Antibacterials: concentration possibly reduced by
rifampicin - avoid.
Antidepressants: concentration possibly reduced by
St John’s wort - avoid.
Antiepileptics: concentration possibly reduced by
carbamazepine, fosphenytoin and phenytoin - avoid.
Antipsychotics: avoid with clozapine, increased risk
of agranulocytosis.
Metabolism
Vismodegib is hepatically metabolised by CYP2C9 and
CYP3A4, however more than 98% of total systemic
vismodegib is not metabolised. Metabolic pathways
of vismodegib include oxidation, glucuronidation, and
pyridine ring cleavage. The two most abundant oxidative
metabolites recovered in faeces are produced in vitro by
recombinant CYP2C9 and CYP3A4/5.
Vismodegib is slowly eliminated by a combination of
metabolism and excretion of parent drug, the majority
is recovered in the faeces (82%). Vismodegib and its
metabolites are eliminated mainly by the hepatic route.

Check Digit Verification of cas no
The CAS Registry Mumber 879085-55-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,9,0,8 and 5 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 879085-55:
(8*8)+(7*7)+(6*9)+(5*0)+(4*8)+(3*5)+(2*5)+(1*5)=229
229 % 10 = 9
So 879085-55-9 is a valid CAS Registry Number.

Oxygenation is a fundamental transformation in synthesis. Herein, we describe the selective late-stage oxygenation of sulfur-containing complex molecules with ground-state oxygen under ambient conditions. The high oxidation potential of the active uranyl cation (UO22+) enabled the efficient synthesis of sulfones. The ligand-to-metal charge transfer process (LMCT) from O 2p to U 5f within the O=U=O group, which generates a UV center and an oxygen radical, is assumed to be affected by the solvent and additives, and can be tuned to promote selective sulfoxidation. This tunable strategy enabled the batch synthesis of 32 pharmaceuticals and analogues by late-stage oxygenation in an atom- and step-efficient manner.
