    摘要: Desalaninebenanomicin A has been synthesized by chemical conversion of benanomicin A. Amino acid derivatives of desalaninebenanomicin A having the general formula (Ia): ##STR1## where R.sup.a represents a hyhrogen atom, a C.sub.1-5 alkyl group, a C.sub.1-5 hydroxyalkyl group, carboxyl group or a lower alkoxycarbonyl group have been synthesized by condensing the 2-carboxyl group of desalaninebenanomicin A with a variety of amino acids. Among the derivatives of the formula (Ia) having antifungal activities, such desalaninebenanomicin A derivatives in which R.sup.a is a C.sub.2-5 alkyl group, a C.sub.2-5 hydroxyalkyl group, carboxyl group or a lower alkoxycarbonyl group are novel semi-synthetic antibiotics having antifungal activities.

    摘要: As a new antifungal and antiviral antibiotic is provided benanomicin A 4"'-O-sulfate or a salt thereof having formula (I) ##STR1## wherein M.sup.1 denotes a mono-valent alkali metal atom or a di-valent alkaline earth metal atom or a hydrogen atom and A denotes an organic base; n is zero when M.sup.1 is an alkali metal atom or alkaline earth metal atom but n is 1 or zero when M.sup.1 is a hydrogen atom, and M.sup.2 denotes a hydrogen atom or an alkali metal atom or an alkaline earth metal atom. This new compound is useful as antifungal agent to treat fungal infections in mammals and as antiviral agent to inhibitingly treat HIV.
