Sulfonamides are unique class of compounds possessing exceptional antibacterial activity. Sulpha drugs were the first effective chemotherapeutic agents to be widely used for the cure of bacterial infection in human and found to be resisted on Mycobacterium tuberculosis, Typhoid and Paratyphoid bacilli etc. A series of novel 10-phenylsulfonyl-2-substituted-4,10 dihydrobenzo[4,5]imidazo[1,2- a]pyrimidin-4-one derivatives obtained from N-sulfonation of 2-substituted-pyrimido[1,2- a]benzimidazol-4(10H)-ones and screened for their in vitro anti-tuberculosis activities against Mycobacterium tuberculosis H37Rv by Microplate Alamar Blue Assay (MABA) method.
磺胺类化合物是一类具有特殊抗菌活性的化合物。磺胺类药物是最早被广泛用于治疗人体细菌感染的有效化疗药物，对结核分枝杆菌、伤寒和副伤寒杆菌等均有耐药性。由2-取代-嘧啶[1,2- A]苯并咪唑-4(10H)- 1 n-磺化得到一系列新的10-苯基磺酰-2-取代-4,10二氢苯并[4,5]咪唑[1,2- A]嘧啶-4- 1衍生物，并采用微孔板Alamar Blue Assay (MABA)方法筛选其体外抗结核活性。

The present histopathology and histochemistry study investigates the effects of clove oil anaesthesia on gills, dendritic organs and skin of a locally available fresh water edible catfish, Clarias gariepinus. The gills, dendritic organs and skin constitute surface organs in C. gariepinus and remain in direct contact with the surrounding water and provide greater surface area of absorption for any xenobiotics including the clove oil hence selected for study. Clove oil extracted from flower buds, leaves and stems of plant Syzygium aromaticum is recently introduced as an effective anaesthetic agent in fishery sector for fulfilling various needs. C. gariepinus of total length 30 ± 2 cm and total weight 200 ± 5 g were exposed to various concentrations of clove oil (LOBA CHEM. PVT. LTD, MUMBAI, Minimum assay 85%) in the range of 0.07 ml/l to 0.3 ml/l. The important behavioural changes observed in C. gariepinus during clove oil exposures include erratic swimming, bubbling, rubbing to side and bottom walls of glass aquarium and protrusion of head above water surface. Fish however become static and horizontal with ceased opercular movements and loss of equilibrium. Clove oil anaesthesia significantly alters the mucogenic property of all surface organs with secretion of more Alcian Blue pH 2.5 positive mucus and slime on surface. Wear and tear and sloughing of epithelial linings of the gills, disintegration of vascular components, oozing of blood on surface of dendritic organs and lifting of gill epithelium are the other toxic manifestations caused in C. gariepinus due to clove oil anaesthesia.
