Efficient One-Pot Synthesis of Doxorubicin Conjugates Through Its Amino Group to Melanotransferrin P97
摘要:
The amino group of doxorubicin I is reacted with bis-NHS-ester linkers 6, or anhydrides 13 to offer in high yield modified doxorubicins 7-12 and 14-16, respectively. Compounds 7-12 are mono-NHS-esters, and can be directly coupled with melanotransferrin (p97), a useful vector with the ability to cross the blood-brain barrier, to yield the expected doxorubicin-p97 conjugates. Upon activating the carboxylic group with BTTU, compound 14-16 could be used in the same reaction. Structurally, the amino group of doxorubicin is covalently bonded to the amino groups of p97. The conjugates are potential candidates for treatment of brain tumors.

Analogs of 6-monoacetyl morphine (6-MAM) are described. These include analogs derivatized at either the C-3 position, the C-6 position, or the nor position of the molecule. These analogs allow for elaboration with linkers terminated by a functional group such as an activated ester, the functional groups being useful for attaching the molecule to other entities such as proteins, polysaccharides, and reporter groups.
