The role of thiazole acetate derivatives on isolated heart and blood vessels in experimental rats

Abstract

Background and objectivesThough various drugs are available in the market for cardiovascular diseases, search for an efficacious and patient friendly drug is an ongoing process. The effect of synthesized thiazole compounds on isolated rat heart and isolated rat blood vessel to determine their potential as newer therapeutic agents. Materials and methodsSix thiazole acetate compounds were examined for their function on isolated heart and blood arteries utilizing standardized experimental models after being characterized and identified in the laboratory. Anesthetized Wistar albino rats' hearts were removed and placed on a Langendorff setup. The percentage change in developed tension and heart rate owing to injecting each thiazole acetate compound in the developed tension and heart rate were seen and recorded in an isolated heart that was mounted in a retrograde fashion using Krebs Henseleit solution. Similarly, anesthetized rats' thoracic aortas were separated, and responses to the standard drug phenylephrine and different thiazole acetate derivatives were examined. The pharmacological effect of the specific thiazole compound was determined by the percentage change in contractile response. ResultEach of the six thiazole acetate derivatives was injected at 1 nM, 10 nM, 100 nM, 1 M, 10 M, and 100 M concentrations. All six (T1 to T6) chemicals investigated in the present study had no significant effect on developed tension or heart rate. There was a nosignificant change in the percentage contraction after injecting 1 nM 3 nM,10 nM, 30 nM, 100 nM, 300 nM, 1 M, 3 M, 10 M, and 30 M,100 M,300 M (cumulative dose) of T1, T3, T4, T5, and T6, while T2 (- ethyl-4-methyl-2-aminothiazole) showed contractile effect in the form of vasoconstrictor activity, which was 30 % of that produced by phenylephrine. Interpretation and conclusionThiazole acetate derivatives did not show any cardiovascular effects except ethyl-4-methyl-2-aminothiazole, which showed a slight vascular contractile response as compared to phenylephrine. A more thorough examination of the utilization of thiazole derivatives is required to establish their potential significance in the cardiovascular system.
