We disclose a study on nucleoside triphosphate (NTP) analogues in which the γ-phosphate is covalently modified by two different biodegradable masking units and d4T as nucleoside analogue that enable the delivery of d4TTP with high selectivity in phosphate buffer (pH 7.3) and by enzyme-triggered reactions in human CD4+ T-lymphocyte CEM cell extracts. This allows the bypass of all steps normally needed in the intracellular phosphorylation. These TriPPPro-nucleotides comprising an acyloxybenzyl (AB; ester) or an alkoxycarbonyloxybenzyl (ACB; carbonate) in combination with an ACB moiety are described as NTP delivery systems. The introduction of these two different groups led to the selective formation of γ-(ACB)-d4TTPs by chemical hydrolysis and in particular by cell extract enzymes. γ-(AB)-d4TTPs are faster cleaved than γ-(ACB)-d4TTPs. In antiviral assays, the compounds are highly active against HIV-1 and HIV-2 in wild-type CEM/O cells and more importantly in thymidine kinase-deficient CD4+ T-cells (CEM/TK-).

Compounds of formula (I) wherein the groups are as defined in the description are disclosed. The compounds of formula (I) are endowed with reversible inhibiting activity of carnitine palmitoyl-transferase and are useful in the preparation of medicaments useful in the pathologies related to a hyperactivity of carnitine palmitoyl-transferase, such as hyperglycemia, diabetes and pathologies related thereto, heart failure, ischemia.
