Reactions of dichlorobis(cyclopentadienyl)titanium(IV) with pyridine dicarboxylic acidsviz. quinolinic acid (QAH2), 2,4-pyridine dicarboxylic acid (PAH2), isocinchomeronic acid (IAH2), cinchomeronic acid (CAH2) and dinicotinic acid (DAH2) were carried out in different stoichiometric ratios. Complexes of the type Cp2Ti(QAH)Cl, Cp2Ti(QAH)2, Cp2Ti(PAH)Cl, Cp2Ti(PAH)2, Cp2Ti(IAH)Cl, Cp2Ti(IAH)2, Cp2Ti(CAH)Cl, Cp2Ti(CAH)2, Cp2Ti(DAH)Cl and Cp2Ti(DAH)2were obtained. These new complexes were characterized on the basis of their elemental analyses, electrical conductance, magnetic moment and spectral data.

Background: (±)-6,8-Dihydroxy-3-undecyl-3,4-dihydroisochromen-1-one is one of the structural analog of several substituted undecylisocoumarins isolated from Ononis natrix (Fabaceae), has been successfully synthesized by direct condensation of homopthalic acid (1) with undecanoyl chloride yields isochromen-1-one (2). Methods: Alkaline hydrolysis of (2) gave the corresponding keto-acid (3), which is then reduced to hydroxy acid (4) then its cyclodehydration was carried out with acetic anhydride to afford 3,4- dihydroisochromen-1-one (5). Followed by demethylation step, the synthesis of target 6,8- dihydroxy-7-methyl-3-undecyl-3,4-dihydroisocoumarin (6) was achieved. Results: In vitro antibacterial screening of all the synthesized compounds were carried out against ten bacterial strains by agar well diffusion method. Conclusion: Newly synthesized molecules exhibited moderate antibacterial activity and maximum inhibition was observed against Bacillus subtilus and Salmonella paratyphi.

Background: : Epilepsy is a genuine neurological turmoil that effects around 50 million individuals around the world. Practically 30% of epileptic patients experience the ill effects of pharmaco-obstruction, which is related with social seclusion, subordinate conduct, low marriage rates, joblessness, mental issues and diminished personal satisfaction. At present accessible antiepileptic drugs have a restricted viability, and their negative properties limit their utilization and cause challenges in patient administration. Gabapentin 1-(aminomethyl)cyclohexane acetic acid, Gbp , (trade name Neurontin), a structural analog of γ-aminobutyric acid (GABA), BCS class 3 drug with having permeability issues. Objective: This work was an attempt to formulate and characterize a new approach to treat epilepsy by targeting to Phospholipase A2 Enzyme through Nanostructured Lipid Carrier. Methods: Docking studied carried out using Accelrys Discovery studio 4.1 Client and gabapentin and phosphotidylcholine were conjugated through chemical conjugation. Nanostructured lipid carrier (NLC) was prepared using hot homogenization technique. Results: The libdock score of Gabapentin- Phosphotidylcholine conjugate (192.535) were found to be more than Gabapentin (77.1084) and Phosphotidylcholine (150.212). For the optimized formulation the particle size (50.08), zeta potential (-1.48), PDI (0.472) and entrapment efficiency (77.8) was observed. The NLC was studies for in-vitro drug release studies and release kinetics. Finally found that the drug release from the NLC followed Higuchi release kinetic and the mode of drug release from the NLC was found to be Non- Fickian diffusion. Conclusion: The formulated Nanostructured lipid carrier of Gabapentin-Phosphotidylcholine conjugate may be able to use to prevent seizure.
