human serum albumin (hsa) is the most abundant plasma protein in the human body. hsa plays an important role in drug transport and metabolism. this protein has a high affinity to a very wide range of materials, including metals such as cu2+ and zn2+, fatty acids, amino acids and metabolites such as bilirubin and many drug compounds. in this study, we investigated the effects of co-amoxiclav, as...

Poly(propargyl pyridinium bromide), a kind of conjugated polyelectrolyte with polyacetylene as the backbone and pyridinium as side groups, was synthesized simply via reaction between pyridine and propargyl bromide under mild conditions. The resultant polymer was characterized by (1)H NMR, elemental analysis, FT-IR, and GPC-MALLS. An alkyne group was confirmed as the end group of the polymer cha...

In the crystal structure of the title compound, C(20)H(39)N(2) (+)·Br(-)·H(2)O, the 1-hexa-decyl-3-methyl-imidazolium cations are stacked along the b axis, forming channels parallel to [100] which are occupied by the bromide anions and water mol-ecules. The crystal is stabilized by O-H⋯Br, C-H⋯O and C-H⋯Br hydrogen-bonding inter-actions, generating a two-dimensional network.

The reaction of NiCl2, K2(i-mnt) (i-mnt2−= 2,2-dicyanoethylene-1,1-dithiolate) and 1-benzyl-4-amino-pyridinium bromide [BzPyNH2]Br affords a nickel complex, [BzPyNH2]2[Ni(i-mnt)2], molecular cata...

albumin has a fundamental role in human body. its main tasks in blood are to regulate osmotic blood pressure, maintaining the ph, and transporting metabolites and drugs throughout the vascular system.  pharmacological studies of the interaction of drugs on hsa are important due to structural and functional changes of this vital protein; thus, here in this research the effect of valproate as a c...

In the title compound, C(11)H(10)N(3)O(4)S(+)·Br(-), the benzene ring makes an angle of 88.4 (2)° with the pyridinium ring. The dihedral angle between the nitro group and the benzene ring is 16.5 (2)°. The ions in the crystal structure are linked by a combination of inter-molecular N-H⋯Br and non-conventional C-H⋯Br and C-H⋯O hydrogen bonds, forming a three-dimensional network.

Mesoporous carbon spheres (MCS) have been fabricated from structured mesoporous silica sphere using chemical vapor deposition (CVD) with ethylene as a carbon feedstock. The mesoporous carbon spheres have a high specific surface area of 666.8 m2/g and good electrochemical properties. The mechanism of formation mesoporous carbon spheres (carbon spheres) is investigated. The important thing is a s...
