Beauty creams and sun blocks are cosmetic products. The majority of creams and lotions are emulsions. An emulsion can be defined simply as two immiscible fluids in which one liquid is dispersed as fine droplets in the other. Beauty creams and sun blocks are widely used in Pakistan as well as all over the world due to look more beautiful, young, fair, wrinkle and spot free skin. Skin care products cause large number of common diseases such as cancer, hormonal disorders, chronic fatigue syndrome, immune disorders, heart disease and sexual problems. Skin cancer is exacerbated by toxic chemicals...

The work presented concerns the preparation, characterization and biological evaluation of Cu(II) and Zn(II) complexes of Schiff bases derived from amoxycillin, cephalexin, sulphamethoxazole and trimethoprim, and salicylalde-hyde and pyridoxal. In these complexes an amino group available in the drug substances was allowed to react with salicylaldehyde and pyridoxal hydrochloride, separately, to obtain Schiff bases which were, subsequently, reacted with Cu(CH3COO)2. H2O and/or Zn(CH3COO)2.2H2O to form Schiff base metal complexes. The ligands and the complexes were characterized by...

2-Thiophenecarboxylic acid hydrazide has been treated with benzaldehyde in 1:1 molar ratio at room temperature in the presence of a suitable solvent to yield Schiff base. Then it has been treated with R2SnCl2/R3SnCl in 1:1 molar ratio to synthesize organotin(IV) complexes under reflux conditions. Organotin(IV) complexes have been characterized by FT-IR and semi-empirical study. FT-IR data explains the tetrahedral arrangement of sulphur donor ligand with tin metal which is further confirmed by semi-empirical study. Least value of dipole moment of complex 3 explain the trans orientation of...

Xylanase enzymes are group of enzymes that can degrade Xylan present in plants. Xylan lignin and cellulose formed a complex matrix in plants. Lignin imparts colour to cellulose and thus eventually imparts colour to paper and pulp. Xylanase facilitates the removal of lignin from the paper pulp thus improves the brightness of paper. Xylanase was produced by Aspergillus niger using different carbon sources. UV irradiation of Aspergillus niger slightly improves the Xylanase activity than native Aspergillus niger. Twenty minutes exposure of Aspergillus niger to UV irradiation was considered...

Tin(IV) and Pd(II) complexes are useful as antibacterial, antiviral, antifungal and antilarvicidal agents. Tin(IV) and Pd(II) complexes are also important as catalyst, water repellent, antifouling agents in paint industry and as fire retardants. Present work focus on the synthesis of tin and palladium complexes, their characterization and biological activity with respect to various fungi and bacteria. Twelve novel triorganotin(IV) complexes have been synthesized by reacting 4-Aminophenol with R3SnCl in (1:1) L/M molar ratio. In the first step ligand was being reacted with R3SnCl in anhydrous...

New Schiff base complexes of Copper, Nickel, Manganese and Zinc derived from Azithromycin with salicylaldehyde have been synthesized. Complexes was synthesized and physico-chemically characterized by solubility testing, melting point and FTIR. The synthesized metal complex was evaluated for antibacterial activity against the multidrug resistant pathogens, such as Gram-negative Escherichia coli and Gram-positive Staphylococcus aureus and antifungal activity in opposition to Aspergillus niger and Aspergillus flavus. The metal complex showed the significant antibacterial and antifungal activity...
