Paragraph 0123; 0139-0141, (2019/01/16)
This invention relates to a near-infrared fluorescent dye, its construction of targeted imaging agent, nano-carrier and anti-cancer drug and application. The invention said near infrared fluorescent dyes with the hydrophilic glycodendrimer through environmental sensitive key connected to form having self-assembling ability of the amphiphilic dendrimers. Hydrophilic dendrimers to lysine and arginine as the skeleton structure, has good tumor target and puts on the membrane. Amphipathic molecule also having a nitro reductase response, can be self-assembled into nano liposome or micelle or vesicle, for gene and/or pharmaceutical carrier, the carrier in the tumor micro-environment de-assembly, and/or drug release gene, in order to realize the purpose of treatment. The amphiphilic molecule also can be in the near-infrared illumination to generate active oxygen, can be used for photodynamic therapy. Said molecule self-assembly after assembling the front and rear reconciliation are fluorescent quenching state, only in the tumor cell nitro reductase under the action of the strong fluorescent will only be, and penetration force is stronger, more precise.

Synthesis and biological evaluation of various colchicine analogues through the mixed-lymphocyte reaction (MLR), lymphoproliferation, and inhibitory effects on the inflammatory genes are described. In addition, a new series of immunosuppressive agents developed on the structural basis of colchicine, as well as their structure-activity relationships is reported. The most potent analogue 20a exhibited an excellent immunosuppressive activity on in vivo skin-allograft model, which is comparable to that of cyclosporin A.

Cyclophilin A (CypA) is a member of cyclophilins, a family of the highly homologous peptidyl prolyl cis-trans isomerases (PPIases), which can bind to cyclosporin A (CsA). CypA plays critical roles in various biological processes, including protein folding, assembly, transportation, regulation of neuron growth, and HIV replication. The discovery of CypA inhibitor is now of a great special interest in the treatment of immunological disorders. In this study, a series of novel small molecular CypA inhibitors have been discovered by using structure-based virtual screening in conjunction with chemical synthesis and bioassay. The SPECS_1 database containing 85,000 small molecular compounds was searched by virtual screening against the crystal structure of human CypA. After SPR-based binding affinity assay, 15 compounds were found to show binding affinities to CypA at submicro-molar or micro-molar level (compounds 1-15). Seven compounds were selected as the starting point for the further structure modification in considering binding activity, synthesis difficulty, and structure similarity. We thus synthesized 40 new small molecular compounds (1-6, 15, 16a-q, 17a-d, and 18a-l), and four of which (compounds 16b, 16h, 16k, and 18g) showed high CypA PPIase inhibition activities with IC50s of 2.5-6.2 μM. Pharmacological assay indicated that these four compounds demonstrated somewhat inhibition activities against the proliferation of spleen cells.
