- Synthesis method of bacterial infection resistant medicine intermediate
-
The invention belongs to the technical field of chemical medicine intermediate synthesis, and particularly relates to a synthesis method of a bacterial infection resistant medicine intermediate. Liquid ammonia and acrylic ester are used as raw materials for preparing a diester type secondary amine compound 1; then, through cyclization, piperidone is prepared; then, scientific reaction catalysts, temperature and time are used; substitution reaction of secondary amine and iso-propyl iodide is used; the target product is synthesized through six-step reaction; the yield of the whole route reachesup to 35 percent.

- Lightening Agents and/or Dyes that Contain Aldehyde(s)
-
Agents for dyeing and/or lightening keratin fibers, in particular human hair, containing, relative to the weight thereof, 0.001 to 15 wt. % of at least one aldehyde of the formula (I): wherein X represents —CH(R2)—SO2—Y—R1, —CR3R4R5, or wherein Y represents —CH(CHO)— or —CH2— or a chemical bond, and wherein each of R1, R2, R3, R4, R5, R6, R7, R8, R9, and R10 independently represents —H or —CN or —F or —Cl or —Br or —I or —CHO or —NH2 or —NO2 or —CF3 or —CCl3 or —CF2CF3 or —CCl2CCl3 or an optionally substituted (C1-C6) alkyl group or a hydroxyalkyl group or a polyhydroxyalkyl group or an optionally substituted (C1-C6) alkylene group, and wherein the agent contains no oxidation dye precursors of developer and coupler type.

- Synthesis of heteroarylpiperazines and heteroarylbipiperidines with a restricted side chain and their affinities for 5-HT1A receptor
-
Heteroarylpiperazine and heteroarylbipiperidine derivatives, bearing a 4-piperidine ring instead of an alkylamino side chain to give the semi-rigidity, were prepared and evaluated for their abilities to displace [3H] 8-OH-DPAT binding to the rat hippocampal synaptic membranes. These compounds showed low to moderate affinities for 5-HT1A receptor, with Ki values ranging from 6912 nM to 232 nM. Of these compounds, 8 b and 15 e exhibited the best affinities for 5-HT1A receptor with Ki values of 232 nM and 338 nM, respectively.
