    ABSTRACT: A biocompatible and biodegradable hydrogel based on a natural polysaccharide was prepared and characterized to evaluate its applicability as effective carrier for controlled protein delivery. The hydrogel exhibited significant pH-sensitivity most favorable for protein release in simulated intestinal medium. It is capable of incorporating considerable amounts of protein drugs (encapsulation efficiency up to 97.6 wt%) following a protein-friendly preparation procedure. It is tested that the hydrogel is able to release two entrapped model protein drugs (bovine serum albumin and lysozyme, respectively) in a controlled manner with full preservation of protein stability and enzymatic activity for lysozyme. Moreover, the insulin-loaded hydrogel was effective in reducing blood glucose level in diabetic animal models. Importantly, the hydrogel showed no evidence of cytotoxicity in vitro and in vivo, rather, it is biodegradable. The synthesized hydrogel shows favorable features as a promising delivery carrier candidate for targeted delivery of protein drugs to the specific sites.

    ABSTRACT: In the present study on the development of new anticonvulsants, fourteen ethyl 2,2-dimethyl-1-(2-substitutedhydrazinecarboxamido)cyclopropanecarboxylate derivatives were synthesized and tested for anticonvulsant activity using the maximal electroshock (MES), subcutaneous pentylenetetrazole (scPTZ) screens, which are the most widely employed seizure models for early identification of candidate anticonvulsants. Their neurotoxicity was determined applying the rotorod test. Two compounds 6f and 6k showed promising anticonvulsant activities in both models employed for anticonvulsant evaluation. The most active compound 6k showed the MES-induced seizures with ED50 value of 9.2 mg/kg and TD50 value of 387.5 mg/kg after intraperitoneally injection to mice, which provided compound 6k with a protective index (TD50 /ED50 ) of 42.1 in the MES test.

    ABSTRACT: In the present study on the development of new anticonvulsants, twenty three 1-(2-arylhydrazinecarboxamido)-2,2-dimethylcyclopropanecarboxylate derivatives were synthesized and tested for anticonvulsant activity using the maximal electroshock (MES), subcutaneous pentylenetetrazole (scPTZ) screens, which are the most widely employed seizure models for early identification of candidate anticonvulsants. Their neurotoxicity was determined applying the rotorod test. Three compounds 6g, 6m and 6w showed promising anticonvulsant activities in both models employed for anticonvulsant evaluation. The most active compound 6m showed the MES-induced seizures with ED(50) value of 9.8 mg/kg and TD(50) value of 332.2 mg/kg after intraperitoneally injection to mice, which provided compound 6m with a protective index (TD(50)/ED(50)) of 33.9 in the MES test.

    ABSTRACT: In the present study on the development of new anticonvulsants, 16 new1-(2-(8-(benzyloxy)quinolin-2-yl)-1-butyrylcyclopropyl)-3-substituted urea derivatives were synthesized and tested for anticonvulsant activity using the maximal electroshock seizure, subcutaneous pentylenetetrazole screens, which are the most widely employed seizure models for early identification of candidate anticonvulsants. Their neurotoxicity was determined by applying the rotorod test. Three compounds 7a, 7e, and 7m showed promising anticonvulsant activities in both models employed for anticonvulsant evaluation. The most active compound 7e showed the maximal electroshock seizure-induced seizures with ED(50) value of 14.3 mg/kg and TD(50) value of 434 mg/kg after intraperitoneal injection to mice, which provided compound 7e with a protective index (TD(50) /ED(50) ) of 30.3 in the maximal electroshock seizure test.

    ABSTRACT: In the present study on the development of new anticonvulsants, 16 new1-(8-(benzyloxy)quinolin-2-yl-6-substituted-4,6-diazaspiro[2,4]heptane-5,7-diones were synthesized and tested for anticonvulsant activity using the maximal electroshock (MES), subcutaneous pentylenetetrazole (scPTZ) screens, which are the most widely employed seizure models for early identification of candidate anticonvulsants. Their neurotoxicity was determined applying the rotorod test. Two compounds 8e and 8j showed promising anticonvulsant activities in both models employed for anticonvulsant evaluation. The most active compound 8e showed the MES-induced seizures with ED(50) value of 8.6 mg/kg and TD(50) value of 365.3 mg/kg after intraperitoneally injection to mice, which provided compound 8e with a protective index (TD(50)/ED(50)) of 26.8 in the MES test.

    ABSTRACT: In the present study on the development of new anticonvulsants, twenty new N-3-arylamide substituted 5,5-cyclopropanespirohydantoin derivatives were synthesized and tested for anticonvulsant activity using the maximal electroshock (MES), subcutaneous pentylenetetrazole (scPTZ) screens, which are the most widely employed seizure models for early identification of candidate anticonvulsants. Their neurotoxicity was determined applying the rotorod test. Three compounds 5d, 5j and 5t showed promising anticonvulsant activities in both models employed for anticonvulsant evaluation. The most active compound 5j showed the MES-induced seizures with ED50 value of 9.2 mg/kg and TD50 value of 421.6 mg/kg after intraperitoneally injection to mice, which provided compound 5j with a protective index (TD50/ED50) of 45.8 in the MES test.
