Studies toward luzopeptins: A key tripeptide subunit selectively deprotectable under neutral conditions
Ciufolini, Marco A.,Valognes, Delphine,Xi, Ning
, p. 3693 - 3696 (1999)
We describe a protocol for the multigram preparation of a tripeptide found in peptin antibiotics. The N-terminus is an azido group, while the C- terminus is an allyl ester. The molecule may be cleanly and selectively deblocked under neutral conditions, fa

Acyl-CoA:cholesterol acyltransferase (ACAT) is the primary enzyme involved in intracellular cholesterol esterification.Arterial wall infiltration by macrophages and subsequent uncontrolled esterification of cholesterol leading to foam cell formation is believed to be an important process which leads to the development of fatty streaks.Inhibitors of the ACAT enzyme may retard this atherogenic process.We have recently discovered a series of imidazoles which are potent in vitro ACAT inhibitors in the J774 macrophage cell culture assay.This paper will describe the design, synthesis, and structure-activity relationship for this very potent series of compounds.

The new lipophilic epipolythiopiperazine-2,5-diones 1,4-dibutylepidithiopiperazine-2,5-dione, 1,4-dibenzylepidithiopiperazine-2,5-dione, 1-benzyl-4-methylepidithiopiperazine-2,5-dione and 3,3'-dithiobis(1,4-dimethylpiperazine-2,5-dione) were synthesized.Unlike the parent compound, the fungal toxin and immunomodulating agent gliotoxin, these compounds did not affect macrophage adherence and cell proliferation in vitro.Like the reduced form of gliotoxin and other simple analogues, these new compounds induce oxidative damage to naked DNA.We conclude that an increase in lipophilicity plays no part in the biological activity of these compounds and in fact abrogates almost all activity.We also synthesized an intermolecular disulfide analogue which also lacked activity.

Compounds of the formula STR1 wherein Y is chlorinated alkyl of 1 to 6 carbon atoms; wherein R is Cn H2n or R2 Cn H2n-1 wherein n is an integer of 1 to 11 and R2 is aralkyl or carboxyalky; and wherein R' is hydrogen, alkyl, haloalkyl, alkaryl or aryl; have fungicidal activity. The compounds can be used in the free acid or salt form.
