ABSTRACT
Potato skin may turn green, purple or sprout when stored improperly.At this time the content of its metabolite sola- nine increases significantly.Although solanine is toxie,it also has certain medicinal value.It has been found that solanine has effects like anti-cancer, anti-inflammation, detumescence, treatment of pulmonary hypertension, and diabetes.This paper searches the relevant literature for the research on the medicinal application of solanine,and systematically summarizes the solanine medicinal value.For a more effective development and utilization of the plant resources,this paper hopes to provide the theoretical and application basis for the development of natural medicine with high efficiency and small adverse reactions in the treatment of cancer, inflammation, tumescence, pulmonary hypertension and diabetes.
ABSTRACT
<p><b>AIM</b>To modify the C-5 side chains of the oxazolidinone derivatives and evaluate their in vitro antibacterial activities preliminarily.</p><p><b>METHODS</b>The title compounds were synthesized in 9 - 12 steps with the starting material 3-fluoroaniline and their in vitro antibacterial activities were examined by using Mueller-Hinton broth dilution method.</p><p><b>RESULTS</b>Thirty new compounds were designed and synthesized, in which eighteen novel title compounds were prepared and their structures were confirmed by 1H NMR and ESI-MS. Eleven compounds showed antibacterial activities to a certain extent, among them compounds 7a, 9a and 11a displayed promising activity.</p><p><b>CONCLUSION</b>Compounds 7a, 9a and 11a were worth further studying.</p>
