Synthesis of new Schiff bases and nucleoside analogues derivatives derived from D-Glucose and their biological activity study
...Show More Authors

Inthis study new derivatives of Schiff bases and nucleoside analogues have been synthesized from the starting material D-glucose after a series of reactions. Derivative 1 was prepared from D-glucose then react with P-bromoacetophenone gave derivative 2 was reacted with dimethyl sulfoxide and acetic anhydride for dehydration a molecule of water gave 3. The spiro ring was prepared at 3-position from the reaction of 3 derivative with 1-phenyl-2–thioureagave 4. The protection group at 1 position was removed by using acetic acid fllowed by periodate oxidation to obtain 6. Reaction of 6 with hydrazide derivative at once and dtriazole derivative at another gave 8 and 9 respectively. Compound 6 was reduced to gave derivative 7. The 1-hydroxylgroup was protected with benzoyl group by using benzoyl chloride to give the derivative 10. Derivative 10 treatment with a mixture of trifluoroacetic anhydride and acetic acid followed by the reaction with trifluoroacetic anhydride gave derivative 11. When derivative 11 treated with silylated uracil derivative the nucleoside analogue 12 was obtained when 11 allowed to react with mercuric theophylline salt in dry xylene, the nucleoside analogue 13 was obtained. The free nucleoside 14 and 15 were obtained when 12 and 13 were allowed to react with sodium methoxide in ethanol respectively. Compounds 8, 9, 14, 15 were exhibited biological activity against E-coli bacteria. Compound 9 exhibited higher degree of activity than the others

Vitamin D receptor rs2228570 and rs1544410 genetic polymorphisms frequency in Iraqi thalassemia patients compared to other ethnic populations
...Show More Authors

Background: The genetic polymorphisms of vitamin D receptor (VDR) have an association with thalassemia development, additionally to the environmental elements that elicited the disorder in the genetically predisposed individuals. As well, VDR functions responsible for the regulation of bone metabolism, such its part in immunity. Aim: The sitting study intended to inspect the association between thalassemia disease and the genetic polymorphisms of VDR among the Iraqi population then compared these findings to other findings of thalassemia patients in other different ethnic populations. Materials and methods: The restriction enzymes Bsm-I and Fok-I were applied to determine the genetic polymorphisms frequencies of VDR by a Polymerase Chain Re
