Novel deazaflavin-cholestane hybrid compounds, 3′,8′-disubstituted-5′-deazacholest-2,4-dieno[2,3-g]pteridine-2′,4′(3′H,8′H)-diones, have been synthesized by condensation reaction between 6-(monosubstituted amino)-pyrimidin-2,4(1H,3H)-diones and 2-hydroxymethylenecholest-4-en-3-one in presence of p-toluenesulfonic acid monohydrate and diphenyl ether. The antitumor activities against human tumor cell lines (CCRF-HSB-2 and KB cells) have been investigated in vitro, and many of these compounds showed promising antitumor activities. Furthermore, molecular docking study using LigandFit within the software package Discovery Studio 1.7 was done for lead optimization of these compounds as potential PTK inhibitors. In general, all of the synthesized steroid-hybrid compounds showed good binding affinities into PTK (PDB code: 1t46).

A series of 3-methyl-10-(substituted-phenyl)flavins was prepared and tested for antimalarial activity against the lethal parasite Plasmodium vinckei in mice. Several of these analogues were found to be effective antimalarial agents. A quantitative structure-activity relationship study was undertaken with 44 analogues and no satisfactory relationship could be established.

Partially deuterated and various substituted flavin and thiaflavin model compounds have been synthesized.For the first time, high-resolution H, D, and 14N ENDOR and TRIPLE resonance experiments in fluid solution have been performed on the paramagnetic derivatives of these compounds.Additionally, valuable information has been obtained about hyperfine anisotropies and molecular structures from ENDOR in rigid matrices.Solid matrix ENDOR studies of native flavoenzymes, namely, "Old Yellow Enzyme" (NADPH dehydrogenase), two flavodoxins, and a methanol oxidase are reported.The ENDOR matrix signals of the various flavoproteins are different in intensity, suggesting that the microenvironments are remarkably different.Applicabilities and limitations of the ENDOR technique in the studies of flavins and flavoenzymes are discussed.
