Novel ruthenium(III) complexes with histamine[RuCl4(dmso-S)(histamineH)]⋅O(1a) and[RuCl4(dmso-S)(histamineH)](1b) have been prepared and characterized by X-ray structure analysis. Their crystal structures are similar and show a protonated amino group on the side chain of the ligand which is not very common for a simple heterocyclic derivative such as histamine. Biological assays to test the cytotoxicity of the compound1bcombined with electroporation were performed to determine its potential for future medical applications in cancer treatment.

Isatins are synthetically versatile substrates, where they can be used for the synthesis of a large variety of heterocyclic compounds. In this, a convenient method has been developed for the conversion of Indoles into Isatins and some heterocyclic derivative were synthesised such as 5- nitro-1H-indole-2,3-dione, 2-methylquinoline-4-carboxylic acid which may be used as raw material for drug synthesis. The general process utilizes the effective method for synthesis of Isatin from Indole is bromination and oxidation with an N-bromosuccinimide-dimethyl sulfoxide reagent. The nitration of Isatin at C-5 takes place by using KNO3, conc. H2SO4, 2-methylquinoline-4-caboxylic acid are usually obtained from pfitzinger reaction.

A heterocyclic derivative of 3-(N-mono-n-lurylaminomethyl) quinazolin-4-one was synthesized and its tribological behavior as an ashless additve without phosphorus and sulphur in liquid paraffin was evaluated using a four-ball tester. On the basis of the experimental results, the novel additive has been found to be quite effective as a potential additive in liquid paraffin. The nature of the film on the rubbed surface was investigated by scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS).

The medium-ring heterocyclic derivative 1,9,10-trimethoxy-5-methyl-1,3,4,5,6,7-hexahydro-2,5- benzoxazonine (6a) was obtained in fair yield from photosolvolysis of 8,9-dimethoxy-4-methyl- 2,3,6,10b-tetrahydro-5H-oxazolo[2,3-a]isoquinolinium iodide (5a) in methanol, together with minor amounts of 3,9,10-trimethoxy-5-methy1-1,3,4,5,6,7-hexahydro-2,5-benzoxazonine (8) and 2-[N-2- {2-(dimethoxymethyl)-4,5-dimethoxyphenyl}ethyl-N-methylamino]ethanol (7). Photosolvolysis products analogous to (6a) were obtained from other related lob-substituted oxazolo[2,3-aliso-quinolinium iodides in high to low yields depending upon the nature of the angular substituent and the presence or absence of substituents in the fused aromatic ring. No methanolysis of the methiodide salts (5a-f) was observed in the absence of ultraviolet irradiation, whereas 1-(2-ethenyl- 4,s-dimethoxypheny1)ethanone (14) was formed on heating (5b) with methanolic potassium hydroxide. Attempted synthesis of 1,2,4,5,6,7-hexahydro-3,5-benzoxazonine derivatives by photosolvolysis of 8,9-dimethoxy-4-methyl-1,5,6,10b-tetrahydro-3H-oxazolo[4,3-a]isoquinolinium iodide (17) in methanol or water was unsuccessful, ring-opened products being obtained in low yield instead.
