Synthesis of Some Thiazolyl and Oxazolyl Quinazoline Derivatives as Potential Anti-Microbial Agents.

Introduction: Quinazoline holds significant importance in pharmaceutical chemistry, which is included in a range of drugs, clinical contenders, and bioactive compounds. N-contain-ing heterocyclic compounds of quinazoline have a wide and distinct range of biopharmaceutical activities.

Methods: A series of newly synthesized heterocyclic compounds, namely, N-(4-substituted ben-zylidene)-2-(2-aminothiazol-4-yl)-6-methylquinazolin-3(4H)-amines (3a'-3e') and N-(4-substi-tuted benzylidene)-2-(2-aminooxazol-4-yl)-6-methylquinazolin-3(4H)-amines (3a-3e), were synthesized starting from 6-methylquinazolin-3(4H)-amine and 4-substituted benzaldehyde and their antibacterial and antifungal properties were evaluated.

Microinvasive oral squamous cell carcinoma: A management protocol.

Microinvasive oral squamous cell carcinoma (MISCC) is the early stage of oral cancer that shows a breach in the basement membrane, and the depth of invasion of the tumour is limited to 0.5-2mm into the papillary stroma. A review of the available data on MISCC was conducted to formulate a management protocol for MISCC and to assess the association of MISCC with oral potentially malignant disorders.

Interbreed variation of dairy cow milk in terms of specific proteome and lipidome for establishing criteria of milk selection.

Background: Ruminant milk is a very complex table food and naturally encrypted with different components possessing various health-promoting characteristics.

Aim: In the present study, we focused on breed-wise compositional difference in milk including various components and release of fatty acids and peptides during digestion.

Methods: First, milk samples were analysed using lactoscan LW milk analyser, MALDI-TOF and gas chromatography.
