Preparation method of 5-tert-butyl-4-ethyl-3-methyl-dihydro-3H-imidazopyridine-(4H)-dicarboxylate
-
Paragraph 0008-0009, (2020/09/23)
The invention relates to a preparation method of 5-tert-butyl-4-ethyl-3-methyl-dihydro-3H-imidazopyridine-(4H)-dicarboxylate, and mainly solves the technical problem that a suitable industrial synthesis method does not exist at present. The method comprises the following three steps: 1, reacting a compound 1 in hydrochloric acid to obtain a compound 2; 2, reacting the compound 2 with an ethyl glyoxylate toluene solution in acetonitrile to obtain a compound 3; and 3, reacting the compound 3 with Boc anhydride and triethylamine in dichloromethane to obtain a final compound 4. The reaction formula is shown in the specification.

Page 91, (2010/02/08)
The present invention relates to compounds that bind to chemokine receptors, and having the formula wherein each A, X, Y, R1, R2 and R3 are substituents. The present invention also relates to methods of using such compounds, such as in treating HIV infection and inflammatory conditions such as rheumatoid arthritis. Furthermore, the present invention relates to methods to elevate progenitor and stem cell counts, as well as methods to elevate white blood cell counts, using such compounds.
NEW OLIGOMERIC CONJUGATES LIABLE TO TRANSFER BIOLOGICAL MOLECULES INTO CELLS
-
, (2008/06/13)
The invention relates to a positively charged oligomeric conjugate, containing an oligomer with a polymerization degree (PD) from 5 to 50, preferably 10 to 40 and more preferably 20, formed from monomeric components having free NH3 in a number equal to or higher than 50 % of the polymerization degree. In particular, the invention provides new oligomeric conjugates of histidylated oligolysine liable to allow the transfer of oligonucleotides, peptides and oligosides into cells.
