antimicrobial lead structure, two analogs (PQ1 and PQ25) were selected for further investigation for biofilm evaluation. Based on the tests performed, there was a significant positive correlation between inhibition of the biofilm attachment and time. The results showed that both analogs (PQ1 and PQ25) are able to reduce biofilm mass. Finally, these findings endorse us further efforts to optimize two phenotypes

The metal salts mediated oxidative free radical reaction of 2-amino-1,4-benzoquinones is described. Imine radicals can be generated by the oxidation of 2-amino-1,4-benzoquinones with Mn(III) and Ag(II). The dimeric products 4 and 14 were formed via the intermolecular radical coupling reaction of the corresponding radical intermediates 5 and 15. In the presence of styrene, twistane 17 was afforded from
