Elevating bioavailability of curcumin via encapsulation with a novel formulation of artificial oil bodies.

Utilization of curcumin has been limited due to its poor oral bioavailability. Oral bioavailability of hydrophobic compounds might be elevated via encapsulation in artificial seed oil bodies. This study aimed to improve oral bioavailability of curcumin via this encapsulation.

Inhibition of lipopolysaccharide-stimulated nitric oxide production in RAW 264.7 macrophages by a synthetic carbazole, LCY-2-CHO.

In activated macrophages, large amounts of nitric oxide (NO) are generated by inducible nitric oxide synthase (iNOS). This is an important mechanism in macrophage-induced cytotoxicity and inflammation. In the present study, a synthetic carbazole compound, 9-(2-chlorobenzyl)-9H-carbazole-3-carbaldehyde (LCY-2-CHO), was found to have an inhibitory effect on lipopolysaccharide (LPS)-stimulated NO generation in RAW 264.

Selective inhibition of protease-activated receptor 4-dependent platelet activation by YD-3.

In the present study, the antiplatelet effect and its mechanism of a new synthetic compound YD-3 [1-benzyl-3-(ethoxycarbonylphenyl)-indazole] were examined. YD-3 inhibited the aggregation of washed human platelets caused by protease-activated receptor (PAR) 4 agonist peptide GYPGKF (IC50 = 0.13 +/- 0.
