Abstract
Aim: Several new dihydropyridine based calcium channel blockers have been synthesized and pharmacologically evaluated for the treatment of hypertension.
Background: The dihydropyridines constitute an important class of calcium channel blockers (CCBs) due to their high potency, wide heterogeneity and tremendous biological usefulness. As a follow-up to our previous studies on 4-aryl-1,4-dihydropyridines as calcium channel blockers for treatment of hypertension, four new series of methyl ethyl ester substituted 1,4-dihydropyridines are reported.
Objectives: The aim of the work is to study the effects of unsymmetrical ester substitutions on calcium channel blocking activity of dihydropyridines (DHPs), while retaining the aminoalkoxy side chain at various positions of the 4-aryl ring. The type and location of the substituents on 4-aryl ring were extensively explored to study the structure activity relationship (SAR) in this series of dihydropyridines as calcium channel blockers.
Methodology: The target DHPs were synthesized using modified Hantzsch condensation and further derivatization. The compounds were screened for their inhibitory potential against L-type calcium channels at a single concentration of 10 μM on NG108-15 cells (Neuroblastoma X Glioma). The most potent DHP 12 was also tested for its vasodilatory activity using rat thoracic aortic rings precontracted with KCl (30 mM) and in vivo antihypertensive activity in rats using tail cuff method.
Results: The newly synthesized DHPs displayed diversified calcium channel blocking activity with compounds 1e, 1h, 2d, 2f, 2h, 6, 9, 11, 12 and 14 producing more than 50% inhibition of veratridine response. 3-Imidazolylpropoxy substituted analogue 12 turned out to be the most potent compound of the four series of compounds and produced fairly higher inhibition (78.6%) of veratridine response in comparison to nifedipine (70%) at 10 µM. In addition, the compound 12 produced potent vasodilatory and antihypertensive properties.
Conclusion: Both location of the side chain and type of substituent on methyl ethyl ester substituted 4-aryl ring affected the response of dihydropyridine derivatives towards L-type calcium channels .

Abstract
Synthesis of a new series of 4-aryl-1,4-dihydropyridines possessing potential calcium channel blocking activity along with good vasodilatory profile is reported. The compounds were synthesized using modified Hantzsch condensation of various aldehydes with methyl 3-aminocrotonate in the presence of a catalytic amount of trifluoroacetic acid and subsequent alkylation with various hydrochlorides of dialkylaminoalkyl chlorides. In vitro calcium channel blocking activity has been evaluated in cultures of neonatal rat cortical neurons by measuring the inhibitory response at L-type calcium channels activated by veratridine. Many compounds exhibited moderate to significant calcium channel blockade around 1 microM. The vasodilatory activity was assessed on isolated rat thoracic aortic rings precontracted by phenylephrine/KCl (30 mM). Most of the compounds produced a concentration-dependent inhibition of the contractile response.

Abstract
A novel dimer of 2-(4-pyridylmethyl)-1-indanone (2) was obtained while carrying out aldol condensation of 1-indanone with pyridine-4-carboxaldehyde in potassium hydroxide. The structure of dimer 3 has been established using various spectral techniques and was screened for its ability to inhibit the cytochrome P(450) enzyme aromatase. The dimer showed strong inhibition of human placental aromatase and was found 3 times more potent (RP = 3, IC(50) = 10.2 microM) as compared to aminoglutethimide (RP = 1, IC(50) = 18.5 microM.
