  • Patent number: 9314539
    Abstract: The present invention is in relation to a composition including nanosphere and histone acetyltransferase (HAT) activator. The nanosphere is carbon nanosphere (CSP) which is intrinsically fluorescent and the HAT activator is N-(4-Chloro-3-trifluoromethyl-phenyl)-2-n-propoxy-benzamide. The N-(4-Chloro-3-trifluoromethyl-phenyl)-2-n-propoxy-benzamide is covalently conjugated with the carbon nanosphere. The present invention further relates to a process for obtaining a composition including carbon nanosphere and Histone acetyltransferase (HAT) activator [N-(4-Chloro-3-trifluoromethyl-phenyl)-2-n-propoxy-benzamide]. The composition is capable of crossing blood brain barrier and inducing histone acetylation in brain. Further, the composition is capable of increasing neurogenesis, as well as improving long-term memory formation.

  • Patent number: 9034387
    Abstract: The present invention provides solution to the problem involved in delivery of active molecules to nucleus. More particularly, the invention provides intrinsically fluorescent and inherently surface functionalized carbon nanospheres which are non-toxic. Also, these carbon nanospheres [CSP] were adsorbed with CTPB [CSP-CTPB] and the adsorbed CSP-CTPB are permeable to cells with nuclear targeting ability. In addition, the present invention provides a composition, a process to prepare the composition comprising CSP with adsorbed active/therapeutic molecules. Further, the instant invention provides a method for delivering active molecules inside a cell nucleus.
