Certain novel piperazine urea derivatives are agonists of the human melanocortin-4 receptor (MC-4R) and, in particular, are receptor-subtype selective agonists of MC-4R. They are useful for the treatment, control, or prevention of diseases and disorders responsive to the activation of MC-4R, such as obesity and diabetes.

The present invention relates to chemical linkers and protecting groups, compounds and compositions containing the chemical linkers or protecting groups, and intermediates and processes that can be used to prepare them. The chemical linkers and protecting groups are based on pyrrolidine and piperidine activating groups, which undergo intramolecular cyclisation upon heating with release of carbon dioxide, thereby releasing the organic compound from a substrate. In particular, those chemical linkers and protecting groups are useful in the solid phase synthesis of oligonucleotides according to the following representative schemes.

The present invention relates to methods for the high fidelity synthesis of oligonucleotides and polynucleotides on a solid surface. In particular, the invention relates to methods of synthesising oligonucleotides, polynucleotides, and doublestranded polynucleotides/nucleic acids, such as DNA and XNA, wherein the process comprises thermally controlled deprotection steps at the 5′-OH of previously coupled nucleosides or nucleotides at selected sites on the surface of the substrate.
