    Abstract: Amoxicillin and Clavulanate potassium oral suspensions are one of antibiotics combination mainly available as dry powders for reconstitution. Made of a β-lactam molecule with a β-lactamase inhibitor, this combination existence can be justified by the potency of Clavulanate potassium which protects Amoxicillin against bacteria producing β-lactamases...

    Abstract: Reaction of either 2-pyrone or 1,4-oxazinone with acetylene follows the sequence of cycloaddition - cycloreversion through concerted mechanism. Transition states for both cycloaddition and cycloreversion pathways have been obtained in both the cases by modelling the reactions at B3LYP/6-31g (d) level. Cycloreversion is faster than cycloaddition in ... Show More
