Aβ Aggregation inhibitors. Part 1: Synthesis and biological activity of phenylazo benzenesulfonamides
摘要:
Phenylazo benzenesulfonamides were designed and synthesized as beta-amyloid (Abeta(40)) fibril assembly inhibitors, and evaluated for inhibition of Abeta(40) aggregation and neurotoxicity using rat cortical neurons. Compound 2 (LB-152) was the most potent compound in this study, and the para-NMe2 group on the end of the phenylazo moiety may play an important role in preventing Abeta(40) fibril formation. LB-152 provides a new lead for further development of potential beta-amyloid aggregation inhibitors to treat AD. (C) 2004 Elsevier Ltd. All rights reserved.

Novel substituted 4-[1H-imidazol-1-yl]benzamides and their use in the treatment of cardiac arrthythmias especially as Class III or combination Class I/III antiarrhythmic agents is described. Pharmaceutical formulations containing such compounds are also disclosed.
A method of establishing a therapeutic window of wound fluid nitric oxide (WFNO) in the wound of a mammal, the method including: obtaining a wound fluid sample from a mammal; analyzing the WFNO level; determining whether the WFNO is at or below a lower threshold level, or is at or above an upper threshold level; wherein the lower threshold level and upper threshold level define the therapeutic window of WFNO; and treating the mammal with a substance that alters the WFNO level such that the therapeutic window of WFNO in the wound is established.
N-(aminoalkyl)-substituted(N or C alkyl)-aryl-4-(methylsylfonylamino)benzamides of the formula ##STR1## wherein R is C.sub.1 -C.sub.4 straight chain alkyl, one of R.sub.1, R.sub.2 and R.sub.3 is a phenyl or naphthyl group and the others are hydrogen, --NR.sub.4 R.sub.5 is a secondary or teritary amino group, X and X.sub.1 are hydrogen or alkyl and n is 0 or 1, are useful as antiarrhythmic agents in the treatment of cardiac arrhythmias especially as combination Class I/Class III agents.
