DNA triplex stabilization property of natural anthocyanins.
The DNA triplex stabilization property of seven natural anthocyanins (five monoglucosides and two diglucosides) has been measured by the mean of triplex thermal denaturation experiments. We haveExpand

Synthesis and evaluation of the in vivo trypanocidal activity of water soluble organotin compounds.
A series of (3-(2-methoxy)ethoxypropyl)tin derivatives were synthesized as potential trypanocidal drugs. The series included an alkyltin trichloride, a dialkyltin dichloride and the correspondingExpand

The in vitro trypanocidal activity of organotin compounds
Summary A series of alkyl (aryl) thio organotin compounds were synthesized as potential trypanocidal drugs. These derivatives were prepared by the treatment of alkyl (or aryl) tin chlorides or oxidesExpand

Synthesis, structure and trypanocidal activity of dibutyltin derivatives of 2-mercaptobenzoxazole and 5-chloro-2-mercaptobenzothiazole
Abstract Single X-ray crystal structure analysis has been determined for the dibutyltin derivatives of 2-mercaptobenzoxazole 1 and 5-chloro-2-mercaptobenzothiazole 2. In both cases, the geometry atExpand

An acetylated monoterpene and a sesquiterpene alcohol from Psiadia anchusifolia.
Two compounds identified as 7,7-dimethyl-2-methylenebicyclo[3.1.1]heptan-6-ol acetate and 6,6,8,9-tetramethyltricyclo[]undec-7-en-2-ol were isolated from the essential oil of the fresh leavesExpand

Synthesis of l-ascorbic acid derivatives as potential bone remodeling agents taking advantage of the Mitsunobu reaction
The synthesis of ascorbic acid derivatives 7a–d is described. Starting from alkenylacetates 1a–d subjected to a hydrosilylation reaction, the resulting hydroxy chloro silanes 3a–d were obtained inExpand

A Novel Synthetic Route to (4-Dimethylaminoaryl)tin Sulfides
Abstract Treatment of tetraaryltin (1) in toluene with SnCl4 at room temperature gave the corresponding aryltin chloride (2). By quenching the reaction mixture with thiols, aryltin sulfides (3) (5a)Expand

Synthesis of 3-Sila Derivatives of l-Ascorbic Acid via Mitsunobu Reaction
Various 3-sila derivatives of L-ascorbic acid were synthesized in satisfactory yields. The ether link was formed by an unusual aspect of the Mitsunobu reaction, without the need of protecting theExpand
