Abstract:

The title molecule, C16H12Cl4N2O2, lies about an inversion center. The symmetry-unique part of the molecule contains an intramolecular O—H...N hydrogen bond. In the crystal, molecules are arranged in corrugated layers parallel to (-101). Weak π–π stacking interactions, with a centroid–centroid diatance of 3.7923 (13) Å, are present.

Abstract:

Substitution reactions of 2,6,10-trichloro-, 2,7,10-trichloro- and 2,8,10-trichloro-10,11-dihydrodibenzo[b,f]thiepin (Vabc) with 1-(2-hydroxyethyl)piperazine, 1-methylpiperazine and 1-benzylpiperazine gave the title compounds IIabc, IIIab and IVab. The new chloro compounds Va and Vb were obtained in 6 steps starting from reactions of 2,5-dichloroacetophenone with 2-chlorothiophenol or 3-chlorothiophenol. Compounds IIabc are 6-chloro, 7-chloro and 8-chloro derivatives of the noncataleptic neuroleptic agent docloxythepin (I). They are almost devoid of cataleptic activity and do not inhibit the apomorphine stereotypies in rats. Compounds IIab have a clozapine-like affinity to dopaminergic receptors in the rat brain striatum; the affinity of IIc is much higher. On the other hand only compounds IIb and IIIa prove a significant antidopaminergic activity in vivo (increase significantly the homovanillic acid level in the rat brain striatum).

Abstract:

1,3-dichloro-2-propanol is a food-borne contaminant reported to cause liver injury. In this study, we evaluated the protective influence of caffeic acid on 1,3-dichloro-2-propanol-induced hepatotoxicity in rats. Rats were randomized into five groups (A–E). Rats received distilled water or caffeic acid (10 or 20 mg/kg body weight) for 7 days. In addition, rats were challenged with 1,3-dichloro-2-propanol on day 7. Caffeic acid prevented 1,3-dichloro-2-propanol-mediated alterations in alkaline phosphatase, alanine and aspartate aminotransferases, albumin and total bilirubin in the serum of rats. Furthermore, caffeic acid lowered superoxide ion, hydrogen peroxide and cytochrome P2E1 while increasing the activities of superoxide dismutase, catalase and glutathione S-transferase in the liver of 1,3-dichloro-2-propanol-treated rats. Caffeic acid raised the levels of nuclear erythroid-related factor 2 (Nrf-2), protein kinase A and phosphoinositide 3-kinase. Caffeic acid pretreatment annulled 1,3-dichloro-2-propanol-mediated alterations in the oxidative stress biomarkers; caspase-3, glutathione, malondialdehyde, protein carbonyl and fragmented DNA, in the liver of rats. Contrastingly, caffeic acid lowered 1,3-dichloro-2-propanol-mediated increase in the levels of nuclear factor-kappa B (NF-κB), tumour necrosis factor-α, interleukin-1β (IL-1β) and IL-6. In addition, caffeic acid preserved the morphological features of 1,3-dichloro-2-propanol-treated rats. Results from this study revealed that caffeic acid protects against 1,3-dichloro-2-propanol-induced hepatotoxicity by enhancing the cytoprotective enzymes through Nrf-2 while lowering inflammation through NF-κB.

The (4,6- dichloro-pyrimidin-2-yl)-amine (2) so produced was then reacted to two moles of phenylthiourea derivatives to yield title compounds (3a-f). The structural assessment of the compounds (3a-f) was made on the basis of spectral data. The synthesized compounds were screened for theirin vitrogrowth inhibiting activity against different strains of bacteriaviz.,B. subtilis, E. coli, P. aeruginosaandS. aureususing agar diffusion technique.

Abstract:

1, 2 - Dichloro benzene on chlorosulphonation by chlorosulphonic acid gives 1, 2 - [dichloro] - benzene sulphonyl chloride which on condensation withp–amino acetophenone gives 1-[acetyl] - 1’ , 2’ - [dichloro] - dibenz sulphonamide derivative. This derivative undergo condensation with 2,4- dichloro benzaldehyde gives 1- [3” - (sub. phenyl) - 2” - propene - 1” - one] - 1’ , 2’ - [dichloro] - dibenz sulphonamide derivative which on reaction with 99% hydrazine hydrate and glacial acetic acid gives 1-[acetyl]-3- [1’ , 2’ - (dichloro) - dibenz sulphonamide] -5 - [2” , 4” - dichloro phenyl] - 2 - pyrazoline derivative. This derivative reacts with various substituted aldehydes to give corresponding substituted chalcone derivatives [1(a-j)]. Now, these chalcone derivatives [1(a-j)] on condensation with urea gives corresponding substituted pyrimidine - 2 - one derivatives [2(a-j)] and on condensation with thio-urea gives corresponding substituted pyrimidine- 2 -thione derivatives [3(a-j)]. Further, these chalcone derivatives [1(a-j)] on reaction with 99% hydrazine hydrate gives 1 - [1’ - (H) - 5’ - (sub. phenyl) - 2’ - pyrazoline]- 3 - [1” , 2” - (dichloro) - dibenz sulphonamide] - 5 - [2’’’ , 4’’’ - dichloro phenyl]-2- pyrazoline derivatives [4(a-j)] as an intermediate compounds, which on condensation with p-acetanilide sulphonyl chloride gives corresponding substituted p - acetanilide sulphonyl derivatives [5(a-j)] and on condensation with benzoyl chloride gives corresponding substituted benzoyl derivatives [6(a-j)]. Structure elucidation of synthesised compounds has been made on the basis of elemental analysis, I.R. spectral studies and 1H N.M.R. spectral studies. The antimicrobial activity of the synthesised compounds has been studied against the cultures “Staphylococcus aureus”, “Escherichia coli” and “Candela albicans”.

Abstract:

In this work, new di-acid monomers 4, 4’-di-carboxillic-4”-bromo-2”, 6”-dimethyl triphenylamine (Ma), 4, 4’- di-carboxylic -4”-chloro-2”, 6”-dimethyl triphenylamine (Mb) and 4, 4’- di-carboxylic -2”,4”-dichloro-6”-methyl triphenylamine (Mc) were synthesized by reaction of p-cyanobenzofluride with three different aromatic amines (4-bromo,2,6-dimethyl aniline, 4-chloro,2,6-dimethyl aniline and 2,4 dichloro, 6- methyl aniline ) via aromatic nucleophilc substitution method to form three di cyano intermediates 4, 4’-Dicyano-4”-bromo-2”, 6”-dimethyl triphenylamine (Da), 4, 4’-dicyano-4”-chloro-2”, 6”-dimethyl triphenylamine (Db) and 4, 4’-dicyano-2”,4”-dichloro-6”-methyl triphenylamine (Dc) which form final di-carboxylic monomers after alkaline hydrolysis. Finally, these monomers react with two different aromatic di amines, phenylene diamins and benzidine respectively via polycondensation reaction to form final polyamides 4"-bromo-2", 6"-dimethyl-triphenylamine-4, 4'-polyphenylbenzamide (Pa), 4”-chloro-2”,6”-dimethyl- triphenylamine-4,4'-polyphenylbenzamide (Pb), 2”,4”-dichloro-6”-methyl-triphenylamine 4,4'- polyphenylbenzamide (Pc),4"-bromo-2",6"-dimethyl triphenylamine-4,4'- polyphenylbiphenylamide (Pd), 2”,4”-dichloro-6”-methyl-triphenylamine-4,4’-polyphenylamide (Pf). The chemical structure of these polymers characterized by FTIR and NMR techniques. All the results of polyamides showed excellent solubility in most polar solvents to form strong thin films. The polyamides possess a good thermal stability with height glass transition temperatures (Tg). Polyamides in DMSO solvent gave strong photoluminescence PL. Thin casting films of these polyamides in cyclic voltammetry (C.V) on glass base of iridium-tin oxide (ITO) as working electrode in dry CH3CN solvent contains 0.1 M of tetrabutylantimoneperchlorate (TBAP) as an Electrolyte gave one redox wave.

Abstract:

The new depsides 3,5-dichloro-2′-O-methylnorstenosporic acid (4), 5-chloro-2′-O-methylanziaic acid (5) and 3,5-dichloro-2′-O-methylnorhyperlatolic acid (6) have been detected in the lichenLecanora lividocinerea and the structures of these metabolites have been established by unambiguous synthesis. In addition, the synthesis of the depside 3,5-dichloro-4-O-demethylplanaic acid (7) is described.

Abstract:

Chlorinations of 2-t-butyl-4-chloro-6-methylphenol(10) and of the mixture of 4,6-dichlorocyclo-hexa-2,ddienones (11) and (12) give the tetrachloro ketones (13)-(15). Reaction of the dichlorocyclohexa-2,4-dienone mixture with nitrogen dioxide gives predominantly dichloro dinitro ketones (17) which rearrange on chromatography to yield the hydroxy dienone (21). X-Ray crystal structures are reported for compounds (13)-(15), (20) and (21).
