Accumulation of methylmalonic acid (MMA) in tissues and biological fluids is the biochemical hallmark of patients affected by the neurometabolic disorder known as methylmalonic acidemia (MMAemia). Although this disease is predominantly characterized by severe neurological findings, the underlying mechanisms of

The Floridian marine cyanobacterium Lyngbya confervoides afforded cyclodepsipeptides, termed tiglicamides A-C (1-3), along with their previously reported analogues largamides A-C (4-6), all of which possess an unusual tiglic acid moiety. Their structures were deduced by one- and two-dimensional NMR combined

[Zn(TA)2(H2O)2] (H-TA=tiglic acid) has been embedded in a framework composed of CECR (CECR=C-ethylcalix[4]resorcinarene) molecules to examine its E-->Z photoisomerization in a periodic framework. The photoisomerization of tiglic acid in CECR-[Zn(TA)2(H2O)2]4 H2O proceeds without the [2+2]-dimerization reaction that often occurs in
