BACKGROUND A number of cytostatic agents have been investigated for the ability to reactivate latent viral reservoirs, which is a major prerequisite for the eradication of HIV-1 infection. Two cytostatic bis(thiosemicarbazonate) gold(III) complexes (designated 1 and 2) were tested for this potential in the U1 latency model of HIV-1 infection. METHODS Cell viability in the presence or absence ...

In this paper the synthesis of curcumin and curcumin derivatives is realised, based on the condensation of benzaldehydes substituted by acetyl acetone. The synthesis way is described and the obtained products are characterised in terms of substituted benzaldehydes, colour, melting point and elemental composition.

Gabapentin is an anticonvulsant widely used in the treatment of epilepsy.An accurate and validated spectrophotometric method was developed as an alternative method to determine gabapentin in pharmaceutical products. This is a simple, accurate, precise, selective and visible spectrophotometric method. The method is based on the measurement of drug absorbance as a result of yellow solution format...

The title compound, C(11)H(11)NO, was synthesized by the reaction of 2-(bromo-meth-yl)benzonitrile and acetyl-acetone in the presence of KOH. In the crystal packing, mol-ecules are linked by inter-molecular N-H⋯O hydrogen bonds into chains running parallel to the b axis. Centrosymmetrically-related chains inter-act further through weak C-H⋯π inter-actions.

The lichen substance, 16-O-acetyl-leucotylic acid (1), was isolated from an acetone extract of Myelochroa aurulenta and found to exhibit antiproliferative activity against HL-60 human leukemia cells. This is the first report on its anti-leukemia activity (EC(50)=21 microM) which is greater than that of leucotylic acid (2) and the structurally related anti-tumor agent, betulinic acid (4).

Acetone extract of aerial parts of Euphorbia marschalliana collected from Iran has been subjected to different chromatography techniques for fractionation and purification. The stereo-structures of the myrsinol esters 15-O-acetyl-3-O-propionyl-5-O-butanoyl-7-O-nicotinoylmyrsinol (1) and 15-O-acetyl-3,5-O-dibutanoyl-7-O-nicotinoylmyrsinol (2) have been probed using ROESY spectroscopy and modifie...

An acetone extract obtained from aerial parts of S. stricta Boiss. & Heldr. apud Bentham, its fractions and phenolic compounds were investigated for their in vivo anti-inflammatory and antinociceptive activities. For the anti-inflammatory activity and for the antinociceptive activity assessment, carrageenan-induced hind paw edema and p-benzoquinone-induced abdominal constriction tests were used...
