A series of trisubstituted pyridines have been prepared that exhibit in vitro leukotriene B4 (LTB4, 1) receptor antagonist activity. Previous disubstituted pyridines from these labs showed high affinity for the LTB4 receptor but demonstrated agonist activity in functional assays (e.g., 2, Ki = 1 nM). Compound 4, the initial lead compound of this new series, showed only modest affinity by comparison
Bongkrekic acid (BKA) is a strong inhibitor of adenine nucleotide translocase (ANT), inducing inhibition of adenosine triphosphate synthesis. We designed and synthesized simplified benzene-ring-containing BKA analogs. The key reaction is the one-pot double Sonogashira reaction, which forms the main skeleton. The analogs were efficiently synthesized in 8–10 longest linear sequence steps. This synthetic
