BACKGROUND The unpredictable side effects of a majority currently used drugs are the substantial issue, in which patients and physicians are forced to deal with. Augmenting the therapeutic efficacy of drugs may prove more fruitful than searching for the new ones. Since recent studies show that new cationic derivatives of polyisoprenoid alcohols (APrens) might exhibit augmenting properties, we i...

Polyisoprenoids or polyprenyls are lipids formed by the sequential condensation of the Ci unit of isopentenyl (3-methylbut-3-enyl) diphosphate with its allylic isomeric form, 3,3-dimethylallyl diphosphate and with further allylic diphosphates resulting from such condensation. The polyprenyl diphosphates function as donors or intermediates in the synthesis of numerous products which include ster...

Dolichols are long-chain unsaturated polyisoprenoids with multiple cellular functions, such as serving as lipid carriers of sugars used for protein glycosylation, which affects protein trafficking in the endoplasmic reticulum. The biological functions of dolichols in plants are largely unknown. We isolated an Arabidopsis thaliana mutant, lew1 (for leaf wilting1), that showed a leaf-wilting phen...
