Novel benzoxazines as inhibitors of angiogenesis

Investigational New Drugs, 2014
Dysregulation of angiogenesis has been associated with many pathological disorders, including cancer; where angiogenesis has been found to be critical for the maintenance and metastasis of tumours. One of the pathways involved in the regulation of angiogenesis is the phosphatidylinositol3-kinase (PI3K) signalling pathway.

Carboxylic acid‐containing benzoxazines as efficient catalysts in the thermal polymerization of benzoxazines

Journal of Polymer Science Part A: Polymer Chemistry, 2008
AbstractThe autocatalytic thermal polymerization behavior of three benzoxazine monomers containing carboxylic acid functionalities is reported. Several mixtures of these carboxylic monomers and 3‐phenyl‐3,4‐dihydro‐2H‐1,3‐benzoxazine were prepared and their thermal polymerization behavior was analyzed by differential scanning calorimetry.

Chitosan/biological benzoxazine composites: Effect of benzoxazine structure on the properties of composites

Reactive and Functional Polymers, 2021
Abstract In this study, two bio-based benzoxazines, PH-f and SA-f, were synthesized and used to prepare benzoxazine/chitosan (CS) composites of PH-f/CS and SA-f/CS and their corresponding curing products poly(PH-f)/CS and poly(SA-f)/CS. Differential scanning calorimeter (DSC) and Fourier-transform infrared spectroscopy (FTIR) spectra show that ...

Highly active antimycobacterial derivatives of benzoxazine

Bioorganic & Medicinal Chemistry, 2010
New 3-(4-alkylphenyl)-4-thioxo-2H-1,3-benzoxazine-2(3H)-ones and 3-(4-alkylphenyl)-2H-1,3-benzoxazine-2,4(3H)-dithiones were synthesized. The compounds were tested for in vitro antimycobacterial activity against Mycobacterium tuberculosis, Mycobacterium avium and two strains of Mycobacterium kansasii.

Induction of apoptosis by benzoxazine analogues

2001
We have evaluated the possible apoptotic effect of benzoxazine (BO) derivatives. For that purpose, we tested the induction of apoptosis by 6-[1-hydroxy-2-(1H-1-imidazolyl)ethyl]-4-methyl-3,4-dihydro-2H-1,4-benzoxazin-3-one (FO4) and 6-[1-[(4-chlorobenzyl)oxy]-2-(1H-1-imidazolyl)ethyl]-4-methyl-3,4-dihydro-2H-1,4-benzoxazin-3-one (FO5) BO analogues in ...
