    摘要: Provided herein are compounds comprising compounds of formula I and/or salts thereof; wherein at least one of R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12, and R13 is fluorine, and the remainder are independently chosen from hydrogen and fluorine; and R14, R15, R16, R17, R18, R19, R20, R21, R22, and R23 are independently chosen from hydrogen and deuterium; with the proviso that when R1, R2, and R3 are fluorine, then at least one of R4, R5, R6, R7, R8, R9, R10, R11, R12, and R13 is fluorine or at least one of R14, R15, R16, R17, R18, R19, R20, R21, R22, and R23 is deuterium. Also provided are medicaments comprising these compounds and methods for treating central nervous system disorders with the compounds and medicaments described herein.

    摘要: A switch to haploid embryogenesis is controlled by the activity of histone deacetylases (HDACs). Blocking HDAC activity with HDAC inhibitors (HDACi), e.g. trichostatin A (TSA), in Brassica napus, B. rapa, B. oleracea, Arabidopsis thaliana and Capsicum annuum male gametophytes leads to a large increase in the proportion of cells that undergo embryogenic growth. In B. napus, treatment with one specific HDACi (SAHA) improves the conversion (i.e. germination) of these embryos into seedlings. Existing methods of culturing microspores of angiosperm plants following stress to produce haploid embryos, haploid plants and double haploid plants can be improved by adding HDACi to the culture medium. Advantageously, species hitherto recalcitrant to haploid embryogenesis via microspore culture are rendered useful when using HDACi. Haploid and double haploid plants are of industrial application in the plant breeding programmes.
