The present invention relates to the use of a compound containing a moiety of formula (I) as a reagent for linking a compound of formula R1—H which comprises a first functional moiety of formula F1 to a second functional moiety of formula F2
wherein X, X′, Y, R1, F1 and F2 are as defined herein. The present invention also provides related processes and products. The present invention is useful for creating functional conjugate compounds, and specifically conjugates in which at least one of the constituent molecules carries a thiol group.

heart failure generated a novel series of acyclic amine inhibitors displaying exceptional potency and PK properties. The series arose through a scaffold hopping approach, which relied on use of an internal H-bond to replace a saturated heterocyclic ring. Optimization of the lead through investigation of both aryl regions revealed approaches to increase potency through substituents believed to enhance separate
The invention relates to novel macrocyclic compounds of the formula (I), in which all of the variables are as defined in the specification, the number of ring atoms included in the macrocyclic ring being 14, 15, 16 or 17, in free base form or in acid addition salt form, to their preparation, to their use as medicaments and to medicaments comprising them.

β-Lactam peptides were envisioned as conformational constraints in antigenic peptides (APs). Three different β-lactam tripeptides of varying flexibility were prepared in solution and incorporated in place of the central part of the altered melanoma associated antigenic peptide Leu27-Melan-A26â35 using solid phase synthesis techniques. Upon TFA cleavage from the solid support, an unexpected opening of the β-lactam ring occurred with conservation of the amide bond. After adaptation of the solid phase synthesis strategy, β-lactam peptides were successfully obtained and both opened and closed forms were evaluated for their capacity to bind to the antigen-presenting class-I MHC HLA-A2 protein system. None of the closed β-lactam peptides bound to HLA-A2, but their opened variants were shown to be moderate to good HLA-A2 ligands, one of them being even capable of stimulating a Melan-A-specific T cell line.
