Effectiveness of teaching medical ethics to medical students on an online platform: An analysis of students' perceptions and feedback.

Medical ethics education along with attitude and communication training has been incorporated into the regular MBBS curriculum in India from 2019, so as to encourage a caring and communicative approach by doctors towards patients. It would be important to understand the relevance of the educational module in the form of cases to ensure an optimal learning process for future students and doctors in the making. We selected three cases and conducted online debates among small groups of second year MBBS students.

Synthesis and structure-antibacterial activity of triazolyl oxazolidinones containing long chain acyl moiety.

A series of new piperazinyl 5-triazolylmethyl oxazolidinones containing long chain acyl group at the piperazine N-4-position were synthesized and evaluated against a panel of standard and clinical isolates of Gram-positive and Gram-negative bacteria. Derivatives having long chain acyl groups with nine or more number of carbon atoms showed significant decrease in antibacterial activity. Antibacterial activity correlated positively with heat of formation of the compounds, but correlated negatively with Clog P values, surface area, ovality and molecular volume.

Structure-antibacterial activity of arylcarbonyl- and arylsulfonyl-piperazine 5-triazolylmethyl oxazolidinones.

A series of novel arylcarbonyl- and arylsulfonyl-piperazinyl 5-triazolylmethyl oxazolidinones were synthesized and tested against a panel of Gram-positive and Gram-negative bacterial clinical isolates. The arylcarbonyl oxazolidinone derivatives showed strong in vitro antibacterial activity against susceptible and resistant Gram-positive pathogenic bacteria and were more active than the arylsufonyl derivatives. Substitution of varied electron-withdrawing and electron-donating groups on the phenyl ring in the arylcarbonyl series did not alter antibacterial activity significantly.

Synthesis and antibacterial activity of new N-linked 5-triazolylmethyl oxazolidinones.

A new series of N-linked 5-triazolylmethyl oxazolidinones with varying substitution at the piperazine nitrogen 4-position were synthesized and tested against a panel of Gram-positive and Gram-negative bacteria including clinical isolates. Most of the compounds showed excellent antibacterial activity against susceptible and resistant Gram-positive organisms. One of the compounds showed enhanced antibacterial activity against Moraxella catarrhalis.
