Synthesis and antimicrobial evaluation of novel 3-(arylideneamino)-3a,8a-dihydroxy-1,3,3a,8a-tetrahydroindeno[1,2-d]imidazole-2,8-diones and their 2-thioxo analogues

The preparation of some novel 3-(arylideneamino)-3a,8a-dihydroxy-1,3,3a,8a-tetrahydroindeno[1,2-d]imidazole-2,8-diones 8(i–xiv) and 3-(arylideneamino)-3a,8a-dihydroxy-2-thioxo-1,3,3a,8a-tetrahydroindeno[1,2-d]imidazol-8(2H)-ones 9(i–xiv) have been reported through one-pot catalyst-free reaction of aldehydes, semicarbazide hydrochloride/thiosemicarbazide with ninhydrin. All the synthesized compounds have been screened for antimicrobial activity and some of them were observed to possess broad spectrum antibacterial potential as well as significant antagonistic potential against fungal pathogens.

Synthesis and in vitro antitumor activity of 1,3,4-oxadiazole derivatives based on benzisoselenazolone

A series of novel 1,3,4-oxadiazole derivatives based on benzisoselenazolone has been prepared and tested for antiproliferative activity in vitro against the cells of human cancer cell lines: SSMC-7721 (human liver cancer cell), MCF-7 (human breast cancer cell) and A549 (human lung cancer cell). All the compounds obtained exhibited antiproliferative activity and showed selective cytotoxicity against different cancer cells. Compounds 7d and 7i showed significant antiproliferative activities against MCF-7 cells, with IC50 values of 1.07 and 1.76/μM respectively. Compound 7d were found to be the most potent compound against SSMC-7721 cells, with IC50 values 4.46/μM.

Green synthesis of 2-amino-5-substituted-1,3,4-oxadiazoles at the platinum anode in acetic acid

The electroorganic synthesis of 2-amino-5-substituted-1,3,4-oxadiazoles from the anodic oxidation of semicarbazone has been carried out at platinum anode in acetic acid under constant potential electrolysis in an undivided cell. This is an environmentally benign method in the field of synthetic organic chemistry. The products are characterized by IR, 1H and 13C NMR, and elemental analysis.

Carbocyclic and heterocyclic substituted semicarbazones and thiosemicarbazones and the use thereof

This invention is related to carbocyclic and heterocyclic substituted semicarbazones and thiosemicarbazones represented by Formula I: or a pharmaceutically acceptable salt or prodrug thereof, wherein: Y is oxygen or sulfur; R1, R21, R22 and R23 are independently hydrogen, alkyl, cycloalkyl, alkenyl, alkynyl, haloalkyl, aryl, aminoalkyl, hydroxyalkyl, alkoxyalkyl or carboxyalkyl; or R22 and R23, together with the N, form a heterocycle; A1 and A2 are independently aryl, heteroaryl, saturated or partially unsaturated carbocycle or saturated or partially unsaturated heterocycle, any of which is optionally substituted; X is one or O, S, NR24, CR25R26, C(O), NR24C(O), C(O)NR24, SO, SO2 or a covalent bond; where R24, R25 and R26 are independently hydrogen, alkyl, cycloalkyl, alkenyl, alkynyl, haloalkyl, aryl, aminoalkyl, hydroxyalkyl, alkoxyalkyl or carboxyalkyl. The invention also is directed to the use of carbocycle and heterocycle substituted semicarbazones and thiosemicarbazones for the treatment of neuronal damage following global and focal ischemia, for the treatment or prevention of neurodegenerative conditions such as amyotrophic lateral sclerosis (ALS), for the treatment and prevention of otoneurotoxicity and eye diseases involving glutamate toxicity and for the treatment, prevention or amelioration of pain, as anticonvulsants, and as antimanic depressants, as local anesthetics, as antiarrhythmics and for the treatment or prevention of diabetic neuropathy and urinary incontinence.
