Synthesis, Spectral investigation [[1]H, [13]C] and Anti-microbial Screening of benzophenone imines

New series of benzophenone imines with general formula Ph[2]-C=NR; R = Benzyl, 4-Fluorobenzyl, Naphthyl, Phenyl, 4-Nitrophenyl were synthesized by condensation of dichlorodiphenylmethane and different aromatic primary amines [1:1] Those imines were characterized by different physiochemical and spectroscopic techniques like melting point, elemental analysis, FT-IR, multinuclear NMR [[1]H, [13]C]. After characterization, imines were subjected to antimicrobial activities. All compounds showed promising activity against different bacterial strains like Escherichia coli, Bacillussubtilis, Pasturellam ultocida and Staphylococcus aureus as well as fungal strains like Alternata alternaria, Ganoderma lucidium, Penicillium notatum and Trichoderma harzianum using Amoxicillin and Flucanazole as a standard drugs respectively

Acoustical behavior of some amino acids in aqueous disodium citrate solutions over temperature range [298.15-313.15] K

Sound velocity, U, and density,Rho, of some amino acids viz. glycine, methionine, phenylalanine and tryptophan were determined in 0.1, 0.2 and 0.3 mol kg[-1]aqueous disodium citrate solutions as a function of concentration at 298-313.15K using DSA 5000M. The experimental data were further used to compute various acoustical parameters such as adiabatic compressibility, beta, apparent molar compressibility, phi[k], partial molar compressibility, phi°[k], transfer adiabatic compressibility, phi[ktr] constant, S[k], and the hydration number, n[h]- The transfer adiabatic compressibility shows the supremacy of hydrophilic-ionic interactions under hydrophobic-ionic interactions. The above-mentioned parameters are relevant for the efficiency of mediation in pharmacology and can be interpreted in terms of structure-making or structure-breaking ability of these amino acids in the solution

Pharmacokinetics for dose proportion; estimation of 250 mg cefaclor tablet in male volunteers

To estimate dose proportion for male volunteers by calculating pharmacokinetics following oral administration of Cefaclor [CCL] 250mg Tablet and to check the relative susceptibility of four bacterial strains. Randomized Clinical Trial, case series. Department of Chemistry and Biochemistry, University of Agriculture, Faisalabad. From Mar 2006 to Feb 2007. Blood samples were collected for the period of 12 hours in heparinized tubes. Collected samples were centrifuged at 3000xg and plasma thus separated was stored at -10°C until further analysis. The CCL plasma concentration was determined via bioassay using disc diffusion method. Pharmacokinetics parameters were calculated using American Pharmacology Organization [APO] computer software. Renal Clearance [CL], volume of distribution [VD], time of Peak [T[max]], maximum plasma concentration [C[max], mean residence time [MRT], absorption half life, elimination half life and the Area Under plasma Concentration [AUC [t0tot12h] showed that the four bacterial strains have different susceptibility against cefaclor and administration of cefaclor at rate of 250 mg as tablet orally thrice daily maintained considerable concentration [>MIC] that prove it to be very effective for the treatment of specific infections in male volunteers
