Halogen-Bonding Strapped Porphyrin BODIPY Rotaxanes for Dual Optical and Electrochemical Anion Sensing

Anion receptors employing two distinct sensory mechanisms are rare. Herein, we report the first examples of halogen-bonding porphyrin BODIPY [2]rotaxanes capable of both fluorescent and redox electrochemical sensing of anions. 1H NMR, UV/visibl

Modular synthesis of heterocyclic carbene precursors

A series of N-heterocyclic carbene precursors, containing an imidazoline or tetrahydropyrimidine framework, were prepared from ω-chloroalkanoyl chlorides. The sequential attachment of nitrogen nucleophiles and subsequent ring closure gave, depending on the reagents used, either the desired dihydroimidazolium and tetrahydropyrimidinium salts or their parent heterocycles. In this latter case, the second substituent was introduced in an alkylation step. The preparation of carbene precursors bearing chiral or bulky substituents was achieved with comparable efficiency.

Leukotriene antagonists

A method for inhibiting the effects of LTB4 comprises administration of an effective amount of a compound represented by the following structural formula (I) STR1 wherein m is 1 or 2; n is 1, 2 or 3; p is 0, 1, or 2; R' is hydrogen or methyl; R is phenyl substituted with A, R1 and R2 wherein R1 and R2 are independently selected from either (1) (S)a --(CH2)b --(T)c --B wherein a is 0 or 1; b is 5 to 12; c is 0 or 1; S and T are independently sulfur, oxygen, or CH2 with the proviso that S or T are not sulfur when p is 1 or 2; and B is C1-4 alkyl, ethynyl, trifluoromethyl, or phenyl optionally monosubstituted with Br, Cl, CF3, C1-4 alkoxy, C1-4 alkyl, methylthio, or trifluoromethylthio; or (2) hydrogen bromo, chloro, methyl, trifluoromethyl, methoxy or nitro; and A is selected from (2) as defined above or a pharmaceutically acceptable salt thereof. Such methods are useful in the treatment of diseases in which LTB4 is a factor.
