NATURAL OR BIO-INSPIRED POLYPHENOLS IN THE SYNTHESIS OF POTENTIAL CHEMOTHERAPEUTIC AGENTS
… my research activity was devoted to lignans and neolignans, synthetized by chemical and/or enzimatic methodology. Hence, in particular, two polyphenol groups were studied, namely benzoxanthene lignans, their related phenazines and bisphenol neolignans; furthermore during the synthesis of …

New synthetic approaches to 8,5'-neolignans
Neolignans, dehydrodimers of phenylpropenes, are natural products that exhibit different biological activities. 8,5’-Neolignans containing a trans- dihydrobenzofuran skeleton are the most abundant neolignans in nature. The published syntheses of trans-dihydrobenzofurans are multistep procedures …

Discovery and Delivery of Bioactive Natural Products
As a part of search for bioactive natural products from the plants in collaboration with the Natural Products Discovery Institute (NPDI), ten plant extracts were investigated for their antiplasmodial activity against Plasmodium falciparum Dd2 strain. Twenty-eight compounds were isolated, and twelve …

Synthesis of lignin-carbohydrate model compounds and neolignans
… are many secondary metabolites such as lignans, neolignans, tannins and terpenoids. The structures of lignans and neolignans are analogous to the interunits of lignin. Lignin is considered an optically inactive polymer, whereas lignans and neolignans are optically active small molecules. Although …

Dai polifenoli naturali agli analoghi sintetici bioattivi.
… e attività biologiche e, tra questi, i neolignani magnololo e honokiolo sono stati studiati per le loro proprietà biologiche. Al giorno d’oggi c’è un crescente interesse per la sintesi di nuovi analoghi inspirati ai due neolignani per incrementare le proprietà biologiche. Pertanto, la …
