A novel series of 4-[N-methyl-N-[(E)-3-[4-(methylsulfonyl)phenyl]-2- propenoyl]amino]benzenesulfonamides has been prepared and evaluated as membrane-bound phospholipase A2 inhibitors. A structure-activity relationship study indicated that the optimum potency was realized with the N-(phenylalkyl)piperidine derivatives 3 and 4. These compounds inhibited the liberation of arachidonic acid from the rabbit heart membrane fraction with IC30 values of 0.028 and 0.009 microM, respectively. Several… 
SYNTHESIS, CHARACTERIZATION AND ANTIMICROBIAL STUDY OF SOME BENZENESULFONAMIDE BASED BIPYRAZOLES
Objectives: To synthesize, characterize and evaluate antimicrobial properties of some benzenesulfonamide based bipyrazole. Methods: The benzenesulfonamide based bipyrazole 1a-d & 2a-f have been
A new nonpeptide tachykinin NK1 receptor antagonist isolated from the plants of Compositae.
TLDR
A novel and potent NK1 receptor antagonist is discovered in the extract of dried flowers of Matricaria chamomilla L. (chamomile) and it has a unique structure of a polyacylated spermine.
Phospholipase A2 inhibitors in development.
TLDR
Indications for which PLA2 inhibitors are being pursued include, sepsis, acute pancreatitis, inflammatory skin and bowel diseases, asthma, and rheumatoid arthritis, and there are no likely clinical candidates emerging from the ranks of cPLA2 and iPLA2 inhibitors in development.
Effects of organometals on cellular signaling. I. Influence of metabolic inhibitors on metal-induced arachidonic acid liberation.
TLDR
It is concluded that the organometals activate PLA2 to some extent via a PT-sensitive pathway, and the necessity of free intracellular Ca2+ for theorganometallic effect is examined.
Phospholipase A2 enzymes: physical structure, biological function, disease implication, chemical inhibition, and therapeutic intervention.
TLDR
The phospholipase A2 (PLA2) superfamily traces its roots to the identification of lytic actions of snake venom at the end of the 19th century and to the late 1980’s when PLA2-like activities were reported in mammalian cells in contrast to extracellular secreted activities from venom and pancreas.
