In our present research we studied physiochemical properties and antimicrobial activity of T. ammi (Trachyuspermum ammi) seeds. The seeds yielded 2.86% essential oil. Refractive index, specific gravity, acid value, and easter values were 1.496, 0.9212, 1.12 and 2.80 respectively. GLC was used to determine the composition of oil. The major component of oil(More)
People relate the neural disorders with either inheritance or psychological violence but there might be some other reasons responsible for the ailment of people that do not have such a background. The present study explains the chronic effect of heavy toxic metals on nervous system. During experimentation, rabbits used as laboratory animals, were given test(More)
The title compound, C(10)H(15)N(3)O, crystallizes in an infinite two-dimensional polymeric network due to inter-molecular N-H⋯O hydrogen bonding. Intra-molecular N-H⋯N and inter-molecular C-H⋯N inter-actions are also present. The 3,4-dimethyl-phenyl unit is disordered over two sites with an occupancy ratio of 0.677 (5):0.323 (5). The dihedral angle between(More)
In the title compound, C(10)H(11)N(3)O(2)S, the thia-zine ring exists in a conformation inter-mediate between twist-boat and half-chair. The dihedral angle between the mean plane of the thia-zine ring and the hydrazide group is 89.45 (13)°. In the crystal, N-H⋯O hydrogen bonds link the mol-ecules into (100) sheets and weak C-H⋯O inter-actions further(More)
We describe the syntheses of half-sandwich complexes of the type [(η(5)-Cp(CONH-R))M(CO)3] with M = Re or (99m)Tc. The R group represents different tri-peptides (tpe) which display high binding affinities for oligopeptide transporters PEPT2. The (99m)Tc complexes were prepared directly from [(99m)Tc(OH2)3(CO)3](+) and Diels-Alder dimerized, cyclopentadienyl(More)
N-(2-Hydroxybenzyl)-2-amino-2-deoxy-D-glucose (NHADG) was synthesized by conjugation of salicylaldehyde to glucosamine. The obtained compound was well characterized via different analytical techniques. Labeling of the synthesized compound with technetium-99m ((99m)Tc) in pertechnetate form ((99m)Tc O4-) was carried out via chelation reaction in the presence(More)
In the title compound, C(10)H(10)N(2)O(2)S, the thia-zine ring approximates to an envelope form with the S atom in the flap position. The amide group attached to the acetate group is almost perpendicular to the mean plane of the thia-zine ring [dihedral angle = 88.83 (8)°]. In the crystal, inversion dimers linked by pairs of N-H⋯O hydrogen bonds occur.(More)
The infrared spectra of pure Mn(CO)(5)X in the region 4000-400 cm(-1) has been obtained in the vapour phase. The observed spectrum has been analyzed to distinguish the fundamental frequencies, the rotational-vibrational and structure, and overtone and combination frequencies. The assignment of the observed vapour phase frequencies to the fundamental modes(More)
