Novel Synthesis of bis Acetylated Hybrid Pyrazoles as Potent Anticandidiasis Agents

Bis acetylated hybrid pyrazoles 을 합성하여 이들 화합물에 대해 녹는점, 원소분석, MS, FT-IR, one-dimensional $^1H,-$ 및 $^{13}C$ -NMR로 분석하였다. 합성한 화합물들에 대해 in vitro 항균활성을 Candida sp. namely Candida albicans, Candida glabrata, Candida parapsilosis, Candida dubliniensis 및 Candida tropicali 균에 대해 수행하였다. Pyrazoles의 페닐고리에 작용기( $-CH_3$ , $-OCH_3$ , -F, -Cl, 및 Br)가 있는 화합물은 Candida species에 대해서 강한 활성을 나타내었다. A new series of bis acetylated hybrid pyrazoles were synthesized and characterized by their melting point, elemental analysis, MS, FT-IR, one-dimensional $^1H$ , and $^{13}C$ NMR spectroscopic data. All the synthesized compounds were tested for their in vitro antifungal activities against Candida sp. namely Candida albicans, Candida glabrata, Candida parapsilosis, Candida dubliniensis and Candida tropicalis. A close inspection of the in vitro anticandidal activity profile in differently electron donating ( $CH_3$ and $OCH_3$ ) and electron withdrawing (-F, -Cl, and Br) functional group substituted phenyl rings of novel hybrid pyrazoles exerted strong anticandidal activity against all the tested Candida species.
