Synthesis, spectral characterization, electrochemical properties and antimicrobial screening of sulfur containing acylferrocenes
摘要:
Several known and eight new sulfur containing acylferrocenes of the general formula FcCO(CH2)(n)SR (where Fc = ferrocenyl, n = 1 or 2 and R = alkyl, 4-bromobenzyl or 2,6-dichlorobenzyl group) were synthesized in order to test their in vitro antimicrobial activity against 11 bacterial and three fungal/yeast strains. It has been shown that only four of the 14 ketones are completely inactive at the tested dose, while the activities of the other ones were noteworthy. All new compounds were well characterized by IR and NMR spectral data, and their electrochemical properties were investigated by cyclic voltammetry. The X-ray crystal structures of two representative ketones are also presented. (C) 2010 Elsevier Ltd. All rights reserved.

ABSTRACTWe investigate the role of information‐based trading in affecting asset returns. We show in a rational expectation example how private information affects equilibrium asset returns. Using a market microstructure model, we derive a measure of the probability of information‐based trading, and we estimate this measure using data for individual NYSE‐listed stocks for 1983 to 1998. We then incorporate our estimates into a Fama and French (1992) asset‐pricing framework. Our main result is that information does affect asset prices. A difference of 10 percentage points in the probability of information‐based trading between two stocks leads to a difference in their expected returns of 2.5 percent per year.
