摘要:The #β-hemoglobinopathies #β-thalassemia (BT) and sickle cell disease (SCD) are the most frequent genetic disorders worldwide. These diseases are caused by mutations causing reduced or abnormal synthesis of the β-globin chain of the adult hemoglobin (Hb) tetramer. Here, the inventors intend to improve HSC-based gene therapy for β-thalassemia and SCD by developing an innovative, highly infectious LV vector expressing a potent anti-sickling β-globin transgene and a second biological function either increasing fetal γ-globin expression (for β-thalassemia and SCD). More particularly, the inventors have designed a novel lentivirus (LV), which carry two different functions: βAS3 gene addition and gene silencing. This last strategy allows the re-expression of the fetal γ-globin genes (HBG1 and HBG2) and production of the endogenous fetal hemoglobin (HbF). Elevated levels of HbF and HbAS3 (Hb tetramer containing βAS3-globin) will benefit the β-hemoglobinopathy phenotype by increasing the total amount of β-like globin that will: (i) reduce the alpha precipitates and improve the alpha/non alpha ratio in β-thalassemia, and (ii) reduce the sickling in SCD. This combined strategy will improve the β-hemoglobinopathy phenotype at a lower vector copy number (VCN) per cell compared to a LV expressing the βAS3 alone.

摘要:New anticonvulsant compounds were synthesized and they include the compounds: DL-2-hydroxy-2-(3′,5′-bistrifluoromethylphenyl)butyramide, DL-2-hydroxy-2-(4′-trifluoromethylphenyl)butyramide, DL-2-hydroxy-2-(3′,4′-dichlorophenyl)butyramide, DL-2-hydroxy-2-(3′-bromophenyl)butyramide, DL-2-hydroxy-2-(4′-bromophenyl)butyramide, DL-2-hydroxy-2-(3′-nitrophenyl)butyramide, DL-3-hydroxy-3-(3′,4′-dichlorophenyl)pentanamide, DL-3-hydroxy-3-(4′-bromophenyl)pentanamide, DL-4-hydroxy-4-(3′,4′-dichlorophenyl) hexanamide and DL-4-hydroxy-4-(4′-bromophenyl)hexanamide. They have a significant anticonvulsant activity against pentylenetetrazol-induced seizures as well as unexpected differences in anticonvulsant activity respect those of the non-halogenated compounds. The invention further provides methods for the synthesis of the DL-hydroxy-alkyl-phenyl amides as exemplified in the examples.
