Reaction of hypochlorous acid (HOCl) with imidazole (Im) taken as a model for the 5-membered ring of guanine, leading to the products 2-chloro- and 2-oxo-imidazoles was investigated at the B3LYP/6-31+G* and B3LYP/AUG-cc-pVDZ levels of density functional theory. For all cases, single point energy calculations were performed at the MP2/AUG-cc-pVDZ level of(More)
BACKGROUND Ribosome biogenesis is an energy consuming and stringently controlled process that involves hundreds of trans-acting factors. Small nucleolar RNAs (snoRNAs), important components of ribosome biogenesis are non-coding guide RNAs involved in rRNA processing, nucleotide modifications like 2'-O-ribose methylation, pseudouridylation and possibly gene(More)
Reactions of peroxynitrite with guanine were investigated using density functional theory (B3LYP) employing 6-31G** and AUG-cc-pVDZ basis sets. Single point energy calculations were performed at the MP2/AUG-cc-pVDZ level. Genuineness of the calculated transition states (TS) was tested by visually examining the vibrational modes corresponding to the(More)
A series of 1,2,4-dithiazole were synthesized from 1,2,4-thiadiazoles in the presence of CS(2) and evaluated for their antimicrobial, anticonvulsant, analgesic and neurotoxicity potential. The compounds provided significant protection against maximal electroshock-induced seizures and seizures induced by 300 mg/kg of subcutaneous pentylenetetrazole(More)
A few flavanones were synthesised by cyclisation of corresponding 3-(heteroaryl)-1(2-hydroxyphenyl) prop-2-en-1-one with sodium acetate in alcohol-water and evaluated for activity. Synthesised compounds were assayed for their in vitro anticancer activity against three human cancer cell lines, mammary adenocarcinoma (MCF7), human colon adenocarcinoma (HT29)(More)
One of the most common central nervous system diseases in tropical countries is cerebral malaria (CM). Malaria is a common protozoan infection that is responsible for enormous worldwide mortality and economic burden on the society. Episodes of Plasmodium falciparum (Pf) caused CM may be lethal, while survivors are likely to suffer from persistent(More)
A total of 60 animals (38 cows, 22 heifers) were selected and were divided into three groups of 20 animals each (containing both anoestrus and repeat breeder) in which treatment was performed for 60 days. Group I: control (farmer practice), T1 group: group I + hormone (double synch), and T2 group: group I + hormone (Estra double synch). The growth(More)
Drought stress is the major environmental constraint contributing to grain yield instability of wheat. In the present study, the recombinant inbred line population derived from DBW43/HI1500 cross was characterized for various morpho-physiological traits as well as grain yield stability analysis under moisture stress. The population was evaluated for grain(More)
A simple, accurate and economic spectrophotometric method for the determination of aripiprazole in tablet formulation is proposed. In the present method acidic solution of the aripiprazole formed colored ion-association complexes with bromocresol green, soluble in chloroform. Yellowish orange chromogen showed λ(max) at 414 nm and obeyed Beer's law in the(More)
Certain 2-(1'-iminothioimido substituted)-1'-substituted phenybenzoic acids (P(1-9)) were synthesized by reaction of phthalic anhydride with benzotriazole, 2-mercapto benzothiazole and 2-p-amino phenyl benzimidazole, respectively (A(1-3)) followed by imine formation with Schiff bases of thiourea with salicylaldehyde, furfuraldehyde and(More)
