- ANTIBODY-DRUG CONJUGATES COMPRISING ANTI-B7-H3 ANTIBODIES
-
The present disclosure relates to antibody-drug conjugates (ADCs) wherein one or more active agents are conjugated to an anti-B7-H3 antibody through a linker. The linker may comprise a unit that covalently links active agents to the antibody. The disclosure further relates to monoclonal antibodies and antigen binding fragments, variants, multimeric versions, or bispecifics thereof that specifically bind B7-H3, as well as methods of making and using these anti-B7-H3 antibodies and antigen-binding fragments thereof in a variety of therapeutic, diagnostic and prophylactic indications

- Replacement of the Benzylpiperidine Moiety with Fluorinated Phenylalkyl Side Chains for the Development of GluN2B Receptor Ligands
-
The 4-benzylpiperidine moiety is a central structural element of potent N-methyl-d-aspartate (NMDA) receptor antagonists containing the GluN2B subunit. To obtain novel GluN2B ligands suitable for positron emission tomography, the benzylpiperidine moiety was replaced with fluorinated ω-phenylalkylamino groups. For this purpose three primary propyl- and butylamines 7 a–c and one butyraldehyde 7 d bearing a fluorine atom and an ω-phenyl moiety were prepared in 3- to 7-step syntheses. Compounds 7 a–d were attached to various scaffolds of potent GluN2B antagonists (scaffold hopping) instead of the original 4-benzylpiperidine moiety. Although benzoxazol-2-ones and indoles with a benzylpiperidine moiety show high GluN2B affinity, the corresponding fluorophenylalkylamine derivatives did not result in high Glu2B affinity. Moderate GluN2B affinity was observed for a 3-(fluoroalkyl)-substituted tetrahydro-1H-3-benzazepine (Ki=239 nm). However, high GluN2B affinity was obtained for the tetrahydro-5H-benzo[7]annulen-7-amines 12 a–c (Ki=17–30 nm). Docking studies resulted in the same binding pose for 12 a as for the lead compound Ro 25-6981. It can be concluded that some GluN2B ligands (benzoxazolones, indoles) do not tolerate replacement of the 4-benzylpiperidine moiety with flexible fluorinated phenylalkyl side chains, but other scaffolds such as tetrahydro-3-benzazepines and -benzo[7]annulenes retain interaction with NMDA receptors containing the GluN2B subunit.

- Demethylation of aromatic methyl ethers using ionic liquids under microwave irradiation
-
An efficient demethylation reaction for aromatic methyl ethers has been developed. Deprotection reactions give high yields with butylpyridinium bromide under microwave irradiation. Basic and acidic functional groups are tolerated if the reaction is performed under acidic conditions.
