    摘要:A method of producing a monomer of a Shiga toxin B-subunit (STxB) protein or of a variant thereof by peptide chemical synthesis, as well as to a method of producing a pentamer of the STxB protein or of the variant thereof. The methods are particularly advantageous as they overcome major issues typically observed in peptide chemical synthesis, including solubility and purity issues.

    摘要:The present invention covers combinations of at least two components, component A and component B, comprising component A being PSMA-TTC, and component B being an antiandrogen selected form AR antagonists such as from cyproterone acetate, bicalutamide, flutamide, nilutamide, enzalutamide, apalutamide, darolutamide or keto-darolutamide, or an AR degrader such as ARV-110, or an ARN-terminal domain binder such as EPI-506, or an antisense oligonucleotide that reduces AR expression such as EZN-4176 or AZD-5312, or an androgen synthesis inhibitor such as abiraterone, particularly abiraterone acetate, seviteronel, galeterone, orteronel or ketoconazole, or a dual AR antagonist and androgen synthesis inhibitor such as ODM-204. Another aspect of the present invention covers the use of such combinations as described herein for the preparation of a medicament for the treatment or prophylaxis of a disease, particularly for the treatment of a hyper-proliferative disease.

    摘要:Compositions and methods for treating diseases and conditions associated with dysregulation of mammalian target of rapamycin complex 1 (mTORC1) are disclosed. The invention is based in part on the discovery that protein mediator of amino acid signaling to mTOR (MORTOR) is involved in amino acid-induced translocation of mTORC1 to lysosomes where MORTOR forms a signaling complex with mTORC1, Ragulator, and Rag GTPases, which controls protein synthesis. In particular, the invention relates to the use of antagonists of MORTOR for treating diseases and conditions associated with dysregulation of mTORC1. Downregulation of expression of MORTOR by RNA interference has been shown to reduce cell proliferation of cancerous cells and may be useful for treating cancer.
