toxicity under normal conditions. In the present study, a library of 14 GSDs was synthesized and screened against PANC-1 human pancreatic cells. Among tested compounds, GSD-11 showed the most potent activity with PC50 a value of 0.72 μM. It also inhibited pancreatic cancer cell migration and colony formation in a concentration-dependent manner. A mechanistic study revealed that this compound can inhibit the

catalytic manifold for the selectiveC–Cbond scission of ketones via the exploitation of the ligand-to-metal charge transfer (LMCT) excitation mode. Through a cooperative utilization of Lewis acid catalysis and LMCT catalysis, the C–Cbond of ketones could be selectively and effectively cleaved, enabling the installation of different functionalities at each carbon of the cleaved C–Cbond through a sequential

Circulardichroism and opticalrotatorydispersion curves of a number of steroid hexahydroindanones have been measured. The compounds were A-nor-5α-androstan-2-ones and 5α-androstan-16-ones carrying methyl groups in positions adjacent to carbonyl. The curves are discussed in relation to the probable conformations of the cyclopentanone ring. Some data on related αβ-unsaturated ketones are also included
