摘要:
A novel conditional gene expression system particularly using the creation and expression of bispecific chimeric molecules including a domain capable of selectively binding a given DNA sequence and a sensing domain capable of specifically binding a transactivator or transrepressor or a transactivator or transrepressor complex.
摘要:
New taxoids having general formula (I), (II), preparation thereof and pharmaceutical compositions containing them. In general formula (I), Ra is hydrogen, hydroxy, alkoxy, acyloxy, alkoxyacetoxy and Rb is hydrogen or Ra and Rb form together with the carbon atom to which they are linked a ketone function; Z is a hydrogen atom or a radical having general formula (II) wherein R1 is an optionally substituted benzoyl radical, thenoyl or furoyl or a radical R2-O-CO- wherein R2 is an alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, bicycloalkyl, optionally substituted phenyl or heterocyclyl radical; R3 is an alkyl, alkenyl, alkynyl, cycloalkyl, phenyl, naphtyl or heterocyclic aromatic radical, and R4 and R5, which are the same or different, represent an alkyl, alkenyl, alkynyl, cycoalkyl, cycloalkenyl, bicycloalkyl, aryl, or heterocyclyl radical, R5 not representing a methyl radical. The new products having general formula (I) wherein Z is a radical of general formula (II) have remarkable antitumoral and antileukaemic properties.
