- Double three bromo 1,3-di-pyridine salt-based propane and its preparation method, method of use, recovery method and application
-
The invention discloses a double tribromo 1,3-bipyridine onium salt dimethylmethane, and a preparation method, an application method, a recovery method and application thereof. The preparation method comprises the following steps: dissolving 1,3-bipyridine onium salt dimethylmethane by using water, and then adding potassium bromide; adding potassium peroxymonosulfate sulfate compound brine solution to prepare a clear solution after dissolving potassium bromide, and then stirring and reacting at -10 to 0 DEG C until solid is separated out; separating out solid, so as to obtain the double tribromo 1,3-bipyridine onium salt dimethylmethane. The product can be used for preparing isothiocyanate, aromatic thiourea or acetanilide. The preparation method disclosed by the invention is mild in condition, and simple to operate the reaction process, and raw materials are easily available. The double tribromo 1,3-bipyridine onium salt dimethylmethane not only can be used as a brominating reagent, but also can be used as organic synthesis intermediates, meanwhile, the reaction efficiency is improved, and the double tribromo 1,3-bipyridine onium salt dimethylmethane is convenient to recover and can be recycled.

- Synthesis of thiophene-2-carboxamidines containing 2-aminothiazoles and their biological evaluation as urokinase inhibitors
-
The serine protease urokinase (uPa) has been implicated in the progression of both breast and prostate cancer. Utilizing structure based design, the synthesis of a series of substituted 4-[2-amino-1,3-thiazolyl]-thiophene-2-carboxamidines is described. Further optimization of this series by substitution of the terminal amine yielded urokinase inhibitors with excellent activities.

- Dihydro-1,2,4-triazin-6(1H)-ones. IV Chemical modification of 3-phenyl-4,5-dihydro-1,2,4-triazin-6(1H)-ones
-
Reaction of 3-phenyl-4,5-dihydro-1,2,4-triazin-6(1H)-one (1) and its 5,5-dimethyl derivative (4) with phosphorus pentasulfide gave the corresponding 6-thiones (2) and (5); methylation of (2) gave the 6-methylsulfanyl-3-phenyl-4,5-dihydro-1,2,4-triazine (3), also obtained by reaction of 6-chloro-3-phenyl-4,5-dihydro-1,2,4-triazine (8) with sodium thiomethoxide. Reaction of (8) with morpholine afforded the 6-(morpholin-4′-yl) derivative (9). Reaction of (1) with isopropyl isocyanate gave N-isopropyl-6-oxo-3-phenyl-1,4,5,6-tetrahydro-1,2,4-triazine-1-carboxamide (19a), and a Mannich reaction of (1) with morpholine and formaldehyde gave the 1-morpholinomethylene derivative (20a). Attempts to effect cycloaddition of 1-methyl-3-phenyl-1,2,4-triazin-6(1H)-one (12) with a benzonitrile oxide failed. Reaction of the thione (2) with 1,3-dipolarophiles gave unstable adducts.

- A facile one-pot preparation of isothiocyanates from aldoximes
-
Isothiocyanates 2a-l were prepared in excellent yields in a one-pot reaction from aldoxime derivatives 1a-l by successive treatment of aldoxime with N-chlorosuccinimide (NCS), thiourea, and triethylamine. The use of HCl/DMF/Oxone system in the reaction instead of NCS was equally effective.

- Synthesis and structure-activity relationships of novel phenylcyanoguanidine derivatives as potassium channel openers
-
3,5-Di-substituted phenylcyanoguanidine derivatives with halogen, cyano, and/or nitro groups at the 3- and 5-positions of the benzene ring exhibited very strong smooth muscle relaxation activity in vitro, as compared to pinacidil. Among them, N-(3-chloro-5-cyanophenyl)-N'-cyano-N''-tert- pentylguanidine (5s) showed 27-fold more potent activity than pinacidil, and exhibited a stronger and more lasting antihypertensive effect than pinacidil by oral administration to spontaneously hypertensive rats. We propose a new pharmacophore model in which the essential factors for binding to the potassium channel are an NH and a bulky alkyl group.
