A novel series of pyrazole derivatives containing indole ring were synthesized from 1-Propyl-1H-indole-2- carbohydrazide and substituted chalcones were refluxed on an oil bath. All the synthesized compounds have been characterized by using elemental analysis, FT-IR, 1H NMR, 13C NMR spectroscopy and further supported by mass spectroscopy. Purity of all the compounds has been checked on thin layer chromatographic plate and HPLC technique. All the synthesized compounds were tested for their antibacterial and antifungal activity (MIC) in vitro by broth dilution method with two Gram-positive bacteria, two Gram-negative bacteria and two fungal strains. The biological activities of the synthesized compounds have been compared with standard drugs Ampicillin and Greseofulvin. The compounds exhibited significant antibacterial and moderate antifungal activities. These compounds can be further exploited to get the potent lead compounds. The detailed synthesis, anti-inflammatory, analgesic and antimicrobial screening of the new pyrazole derivatives containing indole ring are reported
