Felodipine analogs: structure-activity relationships
Journal of Cardiovascular Pharmacology
|January 1, 1987
Summary
Researchers synthesized novel felodipine analogs to assess their oral activity and vascular selectivity. Structure-activity relationships indicate felodipine exhibits near-optimal biological properties for this compound class.
Area of Science:
- Medicinal Chemistry
- Pharmacology
- Cardiovascular Research
Background:
- 3,5-pyridinedicarboxylic acid esters are a class of calcium channel blockers.
- Felodipine is a known dihydropyridine calcium channel blocker used to treat hypertension.
- Analogs of existing drugs are synthesized to explore structure-activity relationships and identify compounds with improved properties.
Purpose of the Study:
- To synthesize novel 3,5-pyridinedicarboxylic acid esters as analogs of felodipine.
- To evaluate the synthesized compounds for peroral activity.
- To assess the vascular selectivity of these felodipine analogs.
Main Methods:
- Chemical synthesis of several 3,5-pyridinedicarboxylic acid [4-(2,3-dichlorophenyl)-1,4-dihydro-2,6-dimethyl-] esters.
- In vitro and/or in vivo assays to determine peroral activity.
- Vascular selectivity assays to compare effects on different blood vessels.
Main Results:
- Several novel felodipine analogs were successfully synthesized.
- The synthesized compounds were tested for their biological activity.
- Structure-activity relationship (SAR) analysis revealed that felodipine possesses biological properties close to the optimum for this class of compounds regarding selectivity and oral activity.
Conclusions:
- Felodipine exhibits near-optimal biological properties within the synthesized class of 3,5-pyridinedicarboxylic acid esters.
- Further research into this class of compounds may yield improved therapeutic agents.
- Understanding SAR is crucial for designing effective cardiovascular drugs.
