Benzoyl urea derivatives that are alpha helical peptides mimetics that mimic BH3-only proteins, compositions containing them, their conjugation to cell-targeting-moieties, and their use in the regulation of cell death are disclosed. The benzoyl urea derivatives are capable of binding to and neutralizing pro-survival Bcl-2 proteins. Use of benzoyl urea derivatives in the treatment and/or prophylaxis of diseases or conditions associated with deregulation of cell death are also described.

Quantitative benzylic mono- and gem-dibromination on primary aromatic amine derivatives have been achieved using molecular bromine and by protecting the amino group as a succinimide moiety. The reactions of N-(o/m/p-tolyl)succinimides 5a-c with 1.25 equivalents of molecular bromine in CCl4 at room temperature furnished the corresponding benzylic monobrominated products 6a-c in 92-94% yields, while with 2.5 equivalents of molecular bromine in refluxing CCl4 gem-dibromo products 7a-c were obtained in 94-96% yields. It is also possible to carry out nuclear bromination in these N-protected primary aromatic amines at an alternate site by using suitably substituted aniline derivatives. Thus the reaction of 3 with 1.25 equivalents of molecular bromine in acetic acid gave the desired monobrominated product 4 in nearly 100% yield.
