O,N,N‘-Trialkylisoureas as Mild Activating Reagents for N-Acylsulfonamide Anchors
摘要:
Prior to detachment of compounds synthesized on sulfonamide based safety-catch linkers, the molecular anchor has to be activated. This is achieved by alkylation of the nitrogen atom of the N-acylsulfonamide using different established protocols. As an addition to the existing repertoire of activating reagents, we suggest the use of O,N,N'-trialkylisoureas. Besides the demonstration of the feasibility of these mild alkylating agents for this purpose, custom-tailored novel O,N,N'-trialkylisoureas prepared from electron-deficient alcohols are reported.

The invention relates to a bifunctional compound that is, on one side, an agonist of the TLR4 and, on the other side, an important inhibitor of the PSMA. Said compound is useful in immunotherapy for the treatment and/or prevention of prostate cancer. Therefore, the invention also relates to the use of the compound and to the pharmaceutical composition comprising it.
The present invention relates to a compound of the general formula: ##STR1## wherein each of R.sup.1 and R.sup.2 which may be the same or different, is e.g. a hydrogen atom, a halogen atom or a lower alkyl group, X is an oxygen atom, a sulfur atom or CH, Y is CH or a nitrogen atom, and A is e.g. a 1-substituted-4-piperidinyl group, a pharmaceutically acceptable salt thereof, a pharmaceutically acceptable anion-exchange product thereof or a hydrate thereof. The compounds of the present invention have chemokine receptor antagonism, and thus they are useful as treating agents for various diseases relating to chemokine, such as acute inflammatory diseases, chronic inflammatory diseases, acquired immune deficiency syndrome, cancer, ischemic reflow disorder and/or arteriosclerosis.
