Manidipine is a calcium channel blocker that is used clinically as an antihypertensive. Target: Calcium ChannelManidipine is a dihydropyridine calcium antagonist, which causes systemic vasodilation by inhibiting the voltage-dependent calcium inward currents in smooth muscle cells. Manidipine was well tolerated in clinical trials, with most adverse effects related to vasodilation [1]. Manidipine is a lipophilic, third-generation dihydropyridine calcium channel antagonist with a high degree of selectivity for the vasculature, thereby inducing marked peripheral vasodilation with negligible cardiodepression. manidipine represents a first-line treatment option for patients with essential mild-to-moderate hypertension [2]. Manidipine has neutral effects on glucose and lipid metabolism and is generally well tolerated. Manidipine thus represents a first-line option for lowering BP in patients with mild-to-moderate hypertension [3].

BMS-538203 is a highly efficient HIV integrase inhibitor and antiviral agent.IC50 value:Target: HIV integraseIn the current study we demonstrate a hit-to-clinical candidate pathway that resulted in 50- and 2000-fold improvements in enzyme-inhibition and antiviral activity without an increase in molecular weight or change in molecular topology. The original hit , 1 (mw = 268) was optimized in a stepwise manner. Potential covalent protein-binding moieties were removed by reducing the number of the ketone groups. High enzyme inhibition activity was achieved by optimizing the aryl-portion of the molecule. Protein binding was reduced by replacing the standard amide by the corresponding methyl-hydroxamide. This eventually led to the discovery of BMS-538203 compound 2 (mw = 269) a highly efficient inhibitor and antiviral agent.

L-Arginine is the nitrogen donor for synthesis of nitric oxide, a potent vasodilator that is deficient during times of sickle cell crisis.Target: OthersL-Arginine is an α-amino acid. It was first isolated in 1886. The L-form is one of the 20 most common natural amino acids. At the level of molecular genetics, in the structure of the messenger ribonucleic acid mRNA, CGU, CGC, CGA, CGG, AGA, and AGG, are the triplets of nucleotide bases or codons that code for arginine during protein synthesis. In mammals, arginine is classified as a semiessential or conditionally essential amino acid, depending on the developmental stage and health status of the individual.L-Arginine is associated with a decrease in cardiac index while stroke index is maintained in patients with severe sepsis. Resolution of shock at 72 hours is achieved by 40% and 24% of the patients in the L-Arginine and placebo cohorts, respectively. L-Arginine (450 mg/kg during a 15-minute period) amplifies and sustains the hyperemia (38%) and increases absolute brain blood flow after eNOS upregulation by chronic simvastatin treatment (2 mg/kg subcutaneously, daily for 14 days) in SV-129 mice.
