54527-89-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 54527-89-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,5,2 and 7 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 54527-89:
(7*5)+(6*4)+(5*5)+(4*2)+(3*7)+(2*8)+(1*9)=138
138 % 10 = 8
So 54527-89-8 is a valid CAS Registry Number.

Asymmetric N-(3,3-diphenylpropyl)aminoalkyl esters of 4-aryl-2,6- dimethyl-1,4-dihydropyridine-3,5-dicarboxylic acids with antihypertensive activity

Leonardi, Amedeo,Motta, Gianni,Pennini, Renzo,Testa, Rodolfo,Sironi, Giorgio,Catto, Alberto,Cerri, Alberto,Zappa, Marco,Bianchi, Giorgio,Nardi, Dante

, p. 399 - 420 (2007/10/03)

A series of asymmetric 4-aryl-1,4-dihydropyridine-3,5-dicarboxylates characterized by the presence of a 3,3-diphenylpropylamino moiety in one of the ester groups were synthesized. They exhibited remarkable antihypertensive activity in spontaneously hypertensive rats as well as affinity for the 1,4- dihydropyridines binding site labelled by 3H-nitrendipine in the calcium channel. Introduction of this bulky and lipophilic amine confers to the whole series an elevated level of antihypertensive activity and a long duration of action, a structure-dependent modulation of the activity being found only in the subset characterized by the presence of a branched propylene bridge between the ester and the amino groups. The presence of the amino group is essential for oral activity. Out of this series, compound 9u (Rec 15/2375- lercanidipine) was selected for clinical development and obtained marketing authorization as an antihypertensive in several countries.

Pharmaceutically useful dihydropyridinyldicarboxylate amides and esters incorporating arylpiperazinylalkyl moities

-

, (2008/06/13)

A series of 1,4-dihydropyridin-3,5-yl dicarboxylic acid amides and esters incorporating an arylpiperazinylalkyl moiety have been prepared possessing the general formula STR1 wherein R4 is cycloalkyl, aryl or hetaryl, generally with electronwithdrawing substituents; R2 and R6 are lower alkyl, alkanol, alkoxyalkyl, or alkylaminoalkyl; R5 is R2 or arylpiperazinylalkyl; X is 0 or NH; Y is lower alkylene, alkoxyalkylene, alkylaminoalkylene; and Z is phenyl, substituted phenyl, pyridinyl, substituted pyridinyl, or pyrimidinyl. Compounds of this series demonstrate activity as calcium and alphaadrenergic blockers in in vitro testing and antihypertensive, antiischemic, and platelet function inhibiting actions in in vivo screens.

Nimodipine: Synthesis and metabolic pathway

Meyer,Wehinger,Bossert,Scherling

, p. 106 - 112 (2007/10/02)

Key step of the synthesis of the calcium antagonistic cerebral vasodilator (±) isopropyl-2-methoxyethyl 1,4-dihydro-2,6-dimethyl-4-(3-nitrophenyl)-3,5-pyridinedicarboxylate (Bay e 9736, nimodipine) is the cyclising Michael addition. A pharmacokinetic study with 14C-nimodipine in the rat revealed as major metabolites the dihydropyridines as well as the pyridines. A potential metabolic pathway is discussed involving ether cleavage and oxidation to the pyridine form as primary biotransformation steps. Reference metabolites were synthesized using 1,4-dihydropyridines with appropriate functionalities as precursors.
