Chitinase 3-like protein 1 (CHI3L-1) and chitotriosidase (CHIT-1) are members of the chitinase family. CHI3L-1 is a newly recognized protein that is secreted by activated macrophages and neutrophils and expressed in a broad spectrum of inflammatory conditions and cancers. In human plasma, CHIT-1 activity has been proposed as a biochemical ...

Secondary and tertiary sulfonamides (R-SO(2)NR(1)R(2)) are defined by the single or double N-alkyl or N-aryl/heteroaryl substitution of the primary sulfonamide respectively. They can be obtained easily by the classical S(N)2 or nucleophile acyl substitution displacements using the appropriate synthones. Many classes of compounds used in therapy present the substituted sulfonamide ...

The red yeasts of the Pucciniomycotina have rarely been transformed with DNA molecules. Transformation methods were recently developed for a species of Sporobolomyces, based on selection using uracil auxotrophs and plasmids carrying the wild-type copies of the URA3 and URA5 genes. However, these plasmids were ineffective in the transformation of ...

Nifedipine is unstable under light and decomposes to a stable nitroso analog, nitrosonifedipine (NO-NIF). The ability of NO-NIF to block calcium channels is quite weak compared with that of nifedipine. Recently, we have demonstrated that NO-NIF reacts with unsaturated fatty acid leading to generate NO-NIF radical, which acquires radical scavenging ...
