摘要:
This invention encompasses a substantially homogeneous lipid chemoattractant released from stressed mammalian tissue which is a neutral lipid which is acid labile and stable to base and is stable in boiling water. This lipid recruits macrophages but not neutrophils to stressed tissue. The invention also encompasses a method for detecting injured tissue by detecting the presence of the above described lipid chemoattractant in body fluids such as urine, serum and saliva. The invention also includes a method for reducing recruitment of macrophages to injured tissue by reducing the amount of the above lipid chemoattractant or by blocking the interaction of this lipid chemoattractant with its macrophage binding site. The addition of this lipid chemoattractant to injured skin tissue promotes healing.
摘要:
A method of preparing a polymer is provided comprising preparing a Baylis-Hillman adduct by reacting an activated alkene with a carbon electrophile; and polymerizing the Baylis-Hillman adduct. The Baylis-Hillman reaction provides an efficient platform for the synthesis of densely functionalized monomers, from which polymers with multiple functional groups can be readily synthesized. It has been discovered that that Baylis-Hillman adducts are versatile monomers for both controlled radical and step-growth polymerizations.
摘要:
A chiral lead catalyst which comprises a lead compound represented by the formula Pb(ORf)2 (wherein Rf represents fluoroalkylsulfonyl) and a chiral crown ether compound having the skeleton represented by the formula (I); and a novel catalyst for asymmetric synthesis which comprises the lead catalyst. The asymmetric-synthesis catalyst, when used to conduct an asymmetric aldol reaction, attains a high yield and high optical selectivity. It has suitability for general-purpose use, and enables a simple reaction operation. Also provided is a method of asymmetric synthesis with the asymmetric-synthesis catalyst.
