Description
Fredericamycin derivatives /
The invention relates to novel fredericamycin derivatives, to drugs containing said derivatives or the salts thereof, and to the use of the fredericamycin derivatives for treating diseases, particularly tumor diseases.
Fredericamycin has been isolated 1981 from Streptomyces griseus, and demonstrates anti-tumor activity.
Fredericamycin and some derivatives of fredericamycin are known.
In Heterocycles 37 (1994) 1893 - 1912, J. Am. Chem. Soc. 116 (1994) 9921 -9926, J. Am.

2000-072752, and in J. Am. Chem. Soc. 123 (2001), various total syntheses of fredericamycin A have been described, some being enantio-selective.
In US 4673768, alkali salts of the fredericamycin A are described. In US
4584377, fredericamycin derivatives are described, particularly derivatives acylated in ring E and F. In US 5,166,208, fredericamycin derivatives are described as well, particularly derivatives carrying thio and amino substituents in ring F. The derivatives are generated semi-synthetically or fully synthetically.
Surprisingly it was found that fredericamycin derivatives, especially those derivatized in ring A, represent potent drugs. Also, a possibility was found to introduce such residues in ring A
semi-synthetically, with which the water solubility and/or the biological effect, the spectrum of action in comparison with fredericamycin, can be significantly increased.
Furthermore, an alternative method was found to make fredericamycin and its derivatives water-soluble by generating cyclodextrin inclusion compounds.
The invention relates to novel fredericamycin derivatives with the general Formula la or Ib:

Preparation of the substances For synthesis of water soluble fredericamycin derivatives, fredericamycin (1) was first hydroxylized with osmium(IV)oxide at the diene side chain.

The reaction can be summarized as a single pot reaction (iodate cleavage of fredericamycin tetrol (2) to fredericamycin aldehyde (4) (see diagram 2) and reduction without isolation of the intermediates to fredericamycin alcohol (11)).

c) NaBH4 Fredericamycin aldehyde (4) can be oxidized with the oxidizing agent sodium chlorite (NaC102), a buffer such as sodium dihydrogenphosphate in presence of an alkene such as 2,3-dimethylbutene with very good yields to fredericamycin carboxylic acid (12).
The usually employed oxidation methods such as those being used in preparative chemistry for the oxidation of aldehydes to carboxylic acids (oxidation with chromium(VI) compounds, manganese(VII) compounds as well as peroxo acid) did not lead to success. Only the use of the above described oxidation method provided the desired product. The literature describes oxidations of 2-pyridone-6-aldehydes with silver ions and potassium permanganate in an alkaline medium. This method, however, is not suited for fredericamycin and its derivatives since fredericamycin (1) contains base-labile (-reactive) groups (OH groups) causing undesired side reactions.
The potassium salt of the fredericamycin acid (13) was obtained according to a common method by stoichiometric neutralization.
Substitution in the B ring Fredericamycin (1) can be reacted with halogenation agents such as N-bromosuccinimide (NBS) and N-iodosuccinimide (NIS) with good yields to the substituted 5-bromo or 5-iodo fredericamycin derivatives (14) and (15) (diagram 6). The fredericamycin aldehyde (4) and (36) can be transformed with elemental bromine, NBS, BrI, NIS, and NCS to the appropriate halogen-substituted fredericamycin aldehyde (37), (38) and (39).
The appropriate fluorine compound is accessible, too.

Surprisingly it has also been found that the methoxy groups in fredericamycin and the derivatives according to the invention can be exchanged under alkali or earth alkali acetate catalysis by oxygen nucleophiles such as alcohols or polyols. Thereby, the alcohols can carry a multitude of different substituents (table 4).

Thereby, the components are stirred with the appropriate primary or secondary amines at room temperature in DMF or in another inert solvent. With aromatic amines, a catalysis with Lewis acids such as stannous(IV)chloride, etc. is required.

The reaction can be summarized as a single pot reaction (iodate cleavage of fredericamycin tetrol (2) to fredericamycin aldehyde (4) (see diagram 2) and reduction without isolation of the intermediates to fredericamycin alcohol (11)).

c) NaBH4 Fredericamycin aldehyde (4) can be oxidized with the oxidizing agent sodium chlorite (NaC102), a buffer such as sodium dihydrogenphosphate in presence of an alkene such as 2,3-dimethylbutene with very good yields to fredericamycin carboxylic acid (12).
The usually employed oxidation methods such as those being used in preparative chemistry for the oxidation of aldehydes to carboxylic acids (oxidation with chromium(VI) compounds, manganese(VII) compounds as well as peroxo acid) did not lead to success. Only the use of the above described oxidation method provided the desired product. The literature describes oxidations of 2-pyridone-6-aldehydes with silver ions and potassium permanganate in an alkaline medium. This method, however, is not suited for fredericamycin and its derivatives since fredericamycin (1) contains base-labile (-reactive) groups (OH groups) causing undesired side reactions.
The potassium salt of the fredericamycin acid (13) was obtained according to a common method by stoichiometric neutralization.
Substitution in the B ring Fredericamycin (1) can be reacted with halogenation agents such as N-bromosuccinimide (NBS) and N-iodosuccinimide (NIS) with good yields to the substituted 5-bromo or 5-iodo fredericamycin derivatives (14) and (15) (diagram 6). The fredericamycin aldehyde (4) and (36) can be transformed with elemental bromine, NBS, BrI, NIS, and NCS to the appropriate halogen-substituted fredericamycin aldehyde (37), (38) and (39).
The appropriate fluorine compound is accessible, too.

Surprisingly it has also been found that the methoxy groups in fredericamycin and the derivatives according to the invention can be exchanged under alkali or earth alkali acetate catalysis by oxygen nucleophiles such as alcohols or polyols.

With aromatic amines, a catalysis with Lewis acids such as stannous(IV)chloride, etc. is required.
