THE ANTICHOLINESTERASE ACTIVITY OF POLYMETHYLENE BIS-QUINOLINIUM SALTS

comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.

heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

Synthesis and Antimicrobial Activity of Sulfur Derivatives of Quinolinium Salts.

A novel method for cleavage of the dithiine ring in 5,12-(dimethyl)-thioqinantrenium bis-chloride 1 "via" reaction with sodium hydrosulfide leads to 1-methyl-3-mercaptoquinoline-4(1H)-thione 2. Further transformation of thiol and thione functions of compound 2 leads to a series of sulfide and disulfide derivatives of quinolinium salts 4 and 6. 1-Methyl-4-chloro-3-benzylthioquinoline chloride 8 ...

The pharmacological actions of polymethylene bistrimethyl-ammonium salts.

Since the classical work of Crum Brown and Fraser, the curariform action of many onium salts has been recognized, and other activities exerted by these compounds have been described, such as those commonly called nicotine-like or muscarine-like. In the present paper an account is given of the actions of members of a polymethylene bistrimethylammonium series, whose general formula is (CH,), N+(C...

Bis(10-meth­oxy­benzo[h]quinolinium) tetra­chloridozinc

In the title compound, (C(14)H(12)NO)(2)[ZnCl(4)], the benzo[h]quinolinium groups are approximately planar, with maximum deviations of 0.049 (8) and 0.056 (9) Å. The meth-oxy groups are stabilized by intra-molecular N-H⋯O hydrogen bonds. The structure also exhibits weak inter-molecular N-H⋯Cl hydrogen bonds between the cations and anions. π-π inter-actions are present between the pyridinium and...
