    <subfield code="a">&lt;p&gt;In this study, Diels-Alder reaction was performed to sulfolene and endo/exo-diacetate compounds. After a series of reactions, new conduritol A and F analogs containing oxo-bridge and naphthalene rings in their structures were synthesized. To the starting compound, bromination, elimination, singlet oxygen reaction, acetylation, selective oxidation with osmium tetroxide (OsO4), and m-chloroperbenzoic acid (m-CPBA), re-acetylation, and finally hydrolysis of the compounds by NH3(g)/MeOH reactions were carried out. 1 H NMR, 13 C NMR, IR, and elemental analysis elucidated the structures of all synthesized compounds. The alpha, (1-glucosidase, and alpha-amylase inhibitory potentials of the new polycyclitols, conduritol A and F analogs, were examined for biological activity. Also, enzyme kinetic studies of well-active compounds were carried out. Compound 30 showed the best inhibition activity against alpha, (1-glucosidase, and alpha-amylase enzymes. Compound 28a showed the best activity against L929 and Capan-1 cell lines, and compound 22 showed the best activity against the A549 fibroblast cell line. Moreover, hemolysis (ASTM F756 standard) and genotoxicity test results were recorded.&lt;/p&gt;</subfield>
