, p. 718 - 730 (2013/09/23)
A new series of 4,5-dihydro-2H-indazoles was synthesized and evaluated for anti-inflammatory activity using formalin-induced paw edema and turpentine oil-induced granuloma pouch bioassays. In addition, the inhibitory activity of cyclooxygenase, ulcerogenic effect, and acute toxicity (ALD50) values were also determined. Compounds 10, 13, 15, 16, 18 and 22 were proved to display distinctive anti-inflammatory profiles with a fast onset of action. They revealed super GI safety profile and are well tolerated by the experimental animals with high safety margin (ALD50 > 300 mg/Kg). The same active compounds exhibited moderate to powerful selectivity profile towards the inhibition of COX-2 enzyme. Docking poses for the most active compounds separately in the active site of human COX-2 enzyme were also obtained.

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.

scheme or table, 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.
