Check Digit Verification of cas no

The CAS Registry Mumber 460746-46-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,6,0,7,4 and 6 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 460746-46:
157 % 10 = 7
So 460746-46-7 is a valid CAS Registry Number.

A facile and scaleable synthesis of ABT-239, a benzofuranoid H3 antagonist

Pu, Yu-Ming,Grieme, Timothy,Gupta, Ashok,Plata, Daniel,Bhatia, Ashok V.,Cowart, Marlon,Ku, Yi-Yin

, p. 45 - 50 (2005)

A facile and scaleable synthesis of a potent and selective histamine H 3 receptor antagonist, ABT-239 (1), was developed starting from commercially available 4′-hydroxy-biphenyl-4-carbonitrile (2). The synthesis comprised four chemical steps and a salt formation step with an overall yield of 40%. A highly selective monoiodination of a phenol was developed and used to prepare iodophenol (3b) in near quantitative yield using NIS in AcOH in the presence of a small amount of H2SO4. A Pd-catalyzed cross coupling reaction of the iodophenols (3b) with butyn-3-ol (4a) provided benzofuran (5) in one step in >80% yield, en route to 1. The new process required no chromatographic purification throughout the synthesis and was successfully demonstrated on scale-up to prepare 1.7 kg of the target ABT-239 (1).

4-(2-[2-(2(R)-Methylpyrrolidin-1-yl)ethyl]benzofuran-5-yl)benzonitrile and related 2-aminoethylbenzofuran H3 receptor antagonists potently enhance cognition and attention

Cowart, Marlon,Faghih, Ramin,Curtis, Michael P.,Gfesser, Gregory A.,Bennani, Youssef L.,Black, Lawrence A.,Pan, Liping,Marsh, Kennan C.,Sullivan, James P.,Esbenshade, Timothy A.,Fox, Gerard B.,Hancock, Arthur A.

, p. 38 - 55 (2007/10/03)

H3 receptor antagonists based on a 2-aminoethylbenzofuran skeleton have been discovered, which are potent in vitro at human and rat H 3 receptors, with Ki values of 0.1-5.8 nM. Analogues were discovered with potent (0.01-1 mg/kg) cognition and attention enhancing properties in animal models. One compound in particular, 4-(2-[2-(2(R)- methylpyrrolidin-1-yl)ethyl]benzofuran-5-yl)benzonitrile (ABT-239), combined potent and selective H3 receptor antagonism and excellent pharmacokinetic and metabolic properties across species, with full efficacy in two behavioral models: a five-trial inhibitory avoidance acquisition model in rat pups at 0.1 mg/kg and a social recognition memory model in adult rats at 0.01 mg/kg. Furthermore, this compound did not stimulate locomotor activity and showed high selectivity for the induction of behavioral efficacy versus central nervous system based side effects. The potency and selectivity of this compound and of analogues from this class support the potential of H3 receptor antagonists for the treatment of cognitive dysfunction.

A new class of potent non-imidazole H3 antagonists: 2-Aminoethylbenzofurans

Cowart, Marlon,Pratt, John K.,Stewart, Andrew O.,Bennani, Youssef L.,Esbenshade, Timothy A.,Hancock, Arthur A.

, p. 689 - 693 (2007/10/03)

2-Aminoethylbenzofurans constitute a new class of H3 antagonists that are more rotationally constrained than most previously reported H3 antagonists. They retain high potency at human and rat receptors, with efficient CNS penetration observed in 35. The SAR of the basic amine moiety was compared in three different series of analogues. The greatest potency was found in analogues bearing a 2-methylpyrrolidine, a 2,5-dimethylpyrrolidine, or a 2,6-dimethylpiperidine.
