RESUMO
CONTEXT: Dyslipidemia is a major risk factor for the development of cardiovascular diseases. Many dyslipidemic patients do not achieve their target lipid levels with the currently available medications, and most of them may experience many side effects. OBJECTIVE: The present work aimed toward identifying a new class of novel nicotinic acid-carboxamide derivatives as promising antihyperlipidemic compounds. MATERIALS AND METHODS: Six novel N-(benzoylphenyl)pyridine-3-carboxamide derivatives were synthesized using acid chloride pathways. All structures were confirmed using 1H-NMR, 13C-NMR, IR, and HRMS. The evaluation of biological activity was conducted using Triton WR-1339-induced hyperlipidemic rats model. RESULTS: This study revealed that some of the newly synthesized novel N-(benzoylphenyl)pyridine-3-carboxamide derivatives mainly C4 and C6 possessed significant antihyperlipidemic activities on lipid components TG and TC (p value <0.05). DISCUSSION AND CONCLUSION: This research opens the door for new potential antihyperlipidemic compounds derived from nicotinic acid that need further optimization of their biological activities.

BACKGROUND AND OBJECTIVES: Increased visit-to-visit variability of BP is associated with cardiovascular disease risk. We examined the association of visit-to-visit variability of BP with renal outcomes among 21,245 participants in the Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We measured mean BP and visit-to-visit variability of BP, defined as SD, across five to seven visits occurring 6-28 months after participants were randomized to chlorthalidone, amlodipine, or lisinopril. The composite outcome included incident ESRD after assessment of SD of systolic BP or ≥50% decline in eGFR between 24 months and 48 or 72 months after randomization. We repeated the analyses using average real variability and peak value of systolic BP and for visit-to-visit variability of diastolic BP. RESULTS: Over a mean follow-up of 3.5 years, 297 outcomes occurred. After multivariable adjustment, including baseline eGFR and mean systolic BP, the hazard ratios for the composite end point were 1.29 (95% confidence interval [95% CI], 0.75 to 2.22), 1.76 (95% CI, 1.06 to 2.91), 1.46 (95% CI, 0.88 to 2.45), and 2.05 (95% CI, 1.25 to 3.36) for the second through fifth (SD of systolic BP =6.63-8.82, 8.83-11.14, 11.15-14.56, and >14.56 mmHg, respectively) versus the first (SD of systolic BP <6.63 mmHg) quintile of SD of systolic BP, respectively (P trend =0.004). The association was similar when ESRD and a 50% decline in eGFR were analyzed separately, for other measures of visit-to-visit variability of systolic BP, and for visit-to-visit variability of diastolic BP. CONCLUSIONS: Higher visit-to-visit variability of BP is associated with higher risk of renal outcomes independent of mean BP.
