A series of pyrido-quinazolines have been synthesised, characterized, and tested for their in vitro epidermal growth factor receptor (EGFR) tyrosine kinase inhibitory activity. The compounds were prepared from Alkylideno/arylideno-bis-ureas. Their final structure of the compounds was elucidated on the basis of spectral studies (IR, 1H NMR, FT-IR, and EI-MS). The cellular EGFR internalization response of selected compounds was evaluated using HeLa cells. Most of the synthesized compounds displayed potent EGFR-TK inhibitory activity and structurally halogenated derivatives had a pronounced effect in inhibiting EGFR internalization.
Synthesis, antibacterial and antifungal activity of some new pyrido quinazolones
Singh,Pandey
, p. 2745 - 2748 (2007/10/03)
Alkylideno/arylideno bis ureas 1 synthesized by ureido-alkylation in the presence of alcohols-which on treatment with p-aminobenzoic acid results in 4-aryl-6-carboxylato-1,2,3,4-tetrahydroquinazolines 2. Reaction of 2 with benzoin in presence of polyphosphoric acid yields 4-aryl-8,9-diphenyl-1,4 dihydro-3H, 7-oxo-1,3-diaza anthracene-2,6-dione 3. Condensation of 3 with aromatic primary amine affords N-aryl-8,9-diphenyl (-2-oxopyrido [g]-4-aryl-2-oxo-1,3-dihydro quinazolines 4. The new compound 4 has been screened for their antibacterial and antifungal activities.
Binding of phenols in the urea-formaldehyde-water system and the role of precondensation stage in the synthesis of polymethyleneurea
Maslosh,Zamashchikov,Bezbozhnaya
, p. 1197 - 1200 (2007/10/03)
The precondensation stage (keeping of a solution of urea and formaldehyde in a neutral medium) in the synthesis of polymethyleneurea is examined experimentally and by mathematical simulation.
