Novel derivatives of fatty acid analogs that have from one to three heteroatoms in the fatty acid moiety which can be oxygen, sulfur or nitrogen, are disclosed in which the carboxy-terminus has been modified to form various amides, esters, ketones, alcohols, alcohol esters and nitriles thereof. These compounds are useful as substrates for N-myristoyltransferase (NMT) and/or its acyl coenzyme, and as anti-viral and anti-fungal agents or pro-drugs of such agents. Illustrative of the disclosed compounds are fatty acid amino acid analogs of the structure ##STR1## in which X is the ethyl or t-butyl ester of an amino acid such as Gly, L--Ala, L--Ile, L--Phe, L--Trp, L--Thr or an amide such as NHCH.sub.2 C.sub.6 H.sub.5 or NH(CH.sub.2).sub.2 C.sub.6 H.sub.5,
本发明揭示了一种脂肪酸类似物的新型衍生物,其中脂肪酸基团中含有一到三个杂原子,可以是氧、硫或氮,并且羧基末端已经被修饰成各种酰胺、酯、酮、醇、醇酯和腈。这些化合物可用作N-肌醇化转移酶(NMT)及/或其酰基辅酶的底物,以及抗病毒和抗真菌剂或这些剂的前药。其中一些化合物的结构为脂肪酸氨基酸类似物,如下式所示:##STR1## 其中X为氨基酸的乙酰或叔丁基酯,例如甘氨酸、L-丙氨酸、L-异亮氨酸、L-苯丙氨酸、L-色氨酸、L-苏氨酸或酰胺,例如NHCH.sub.2 C.sub.6 H.sub.5或NH(CH.sub.2).sub.2 C.sub.6 H.sub.5。
