New Pyrazole-Based Tetrazole Derivatives: Synthesis, Characterization, and Their Vasorelaxant and α-Amylase...

Area of Science:

• Medicinal Chemistry
• Organic Synthesis
• Pharmacology

Background:

• Pyrazole and tetrazole scaffolds are prevalent in pharmacologically active molecules.
• Developing novel compounds with dual therapeutic potential is a key area of research.

Purpose of the Study:

• To synthesize and characterize novel linear pyrazole-based tetrazole derivatives.
• To evaluate the vasorelaxant and anti-diabetic activities of these new compounds.

Main Methods:

• Synthesis via equimolar condensation of pyrazole and tetrazole precursors.
• Structural confirmation using NMR spectroscopy and high-resolution mass spectrometry (HRMS).
• In vitro assessment of vasorelaxant activity (E%) and α-amylase inhibition (IC50).

Main Results:

• Ten new pyrazole-based tetrazole derivatives (1-10) were successfully synthesized.
• Compound 4 displayed the highest vasorelaxant activity (67% inhibition).
• Compounds 2 and 6 showed significant α-amylase inhibition, comparable to acarbose.

Conclusions:

• The synthesized pyrazole-based tetrazole derivatives possess significant vasorelaxant and anti-diabetic potential.
• These findings warrant further investigation for potential therapeutic applications.
