A simple, reliable and rapid method for preconcentration and modification of silica gel with Isopropyl 2-[(isopropoxy carbothioyl)disulfanyl]ethanethioate(IIDE) in order to prepare an effective sorbent for the preconcentration and determination of lead. The sorption capacity of Isopropyl 2[(isopropoxy carbothioyl)disulfanyl]ethanethioate(IIDE)-modified silica-gel (IIDE MS) was 82.34 mg.g  -1 a...

Behavior authoring for computer games involves writing behaviors in a programming language and then iteratively refining them by detecting issues with them. The main bottlenecks are a) the effort required to author the behaviors and b) the revision cycle as, for most games, it is practically impossible to write a behavior for the computer game AI in a single attempt. The main problem is that th...

Palladium-catalysed cis- and trans-silaboration of terminal alkynes has been developed via the addition of (chlorodimethylsilyl)pinacolborane, followed by a one-pot conversion of the chloro group on the silicon atom to an isopropoxy group.

Beta-carbolines are a class of drug which can interact with a high affinity with the benzodiazepine (BDZ) binding site of the GABAA receptor. The present paper, aimed at obtaining a deeper insight into the structure-properties relationships of this class of molecules, reports the crystal structures of four beta-carbolines: ZK93423 (3-carboethoxy-4-methoxymethyl-6-benzyloxy-beta-carboline), ZK91...

Arylimidamide (AIA) compounds containing two pyridylimidamide terminal groups (bis-AIAs) possess outstanding in vitro antileishmanial activity, and the frontrunner bis-AIA DB766 (2,5-bis[2-(2-isopropoxy)-4-(2-pyridylimino)aminophenyl]furan) is active in visceral leishmaniasis models when given orally. Eighteen compounds containing a single pyridylimidamide terminal group (mono-AIAs) were synthe...
