Novel chalcone based 6-carbethoxy-2-cyclohexen-1-one and 2H-indazol-3-ol derivatives were synthesized and characterized by using spectral techniques like IR, 1H NMR, 13C NMR, COSY, DEPT, and GC-MS. All these compounds were screened for anti-fungal, anti-bacterial and anti-oxidant activity. Cyclohexenone derivatives, in general, showed better anti-fungal and anti-bacterial activity than parent chalcones. Whereas, all the Indazole derivatives showed very good anti-oxidant activity and some were also found to be active as anti-bacterial agent. Among the screened compounds, 15 was found to be most active as anti-fungal agent (against Rhizoctonia solani, LC 50 = 2.36 μg mL-1), 15b was found to be most active anti-bacterial agent (against Klebsiella pneumonia, MIC = 24.68 μg mL -1) and 14b emerged as most active anti-oxidant (IC50 = 19.81 μg mL-1).

An array of novel spiro imidazolidine derivatives was synthesized in dry media and was screened for their anti-microbial activities. Structure-activity relationship results revealed that compounds 22, 23 against P.aeruginosa, 24 against S.aureus, 24, 25 against K.pneumonia, 27 against S.aureus, β-H.streptococcus, 29 against M.luteus, K.pneumonia, 29, 30 against P.vulgaris exhibited excellent antibacterial activity at a minimum inhibitory concentration (MIC) value of 6.25 μg/mL. Compound 23 against M.gypseum, 25, 29 against Candida 6 and 29, 30 against C.albicans revealed excellent antifungal activity at a MIC value of 6.25 μg/mL.
Synthesis, spectral analysis, and in vitro microbiological evaluation of ethyl 7,9-diaryl-1, 4-diazaspiro[4.5]dec-9-ene-6-carboxylates as a new class of antibacterial and antifungal agents

, p. 575 - 583 (2012/01/19)
A series of novel ethyl 7,9-diaryl-1,4-diazaspiro[4.5]dec-9-ene-6- carboxylates was synthesized by the reaction of ethyl 4,6-diaryl-2-oxocyclohex- 3-ene-1-carboxylates with ethylenediamine in the presence of p-toluenesulfonic acid without a solvent under focused microwave irradiation. The title compounds were screened for their antimicrobial activities against a spectrum of clinically isolated microorganisms.
