The present disclosure provides novel macrocyclic peptides which inhibit the PD-1/PD-L1 and PD-L1/CD80 protein/protein interaction, and thus are useful for the amelioration of various diseases, including cancer and infectious diseases.
their potential in biotechnology and their production of metabolites of interest. Lichens are a promising source of new bacterial strains, especially Actinobacteria, which afford a broad chemical diversity. In this context, the culture medium of the actinobacterium Nocardia ignorata, isolated from the terrestrial lichen Collema auriforme, was studied. The strain was cultivated in a BioFlo 115 bioreactor

The present invention is directed at bouvardin analogs arid related compounds for the treatment of disorders including cancer. Provided herein are bouvardin analogs and related compounds, pharmaceutical compositions and kits comprising at least one bouvardin analog or related compound, and methods for treating disorders including cancer. In some aspects the compounds inhibit translation elongation at the ribosome. The compounds are used in combination with radiation therapy or with known chemotherapeutic compositions.

Reaction conditions considered to be typical in Suzuki couplings can cause significant (up to 34% of the unwanted enantiomer) loss of optical purity in sensitive substrates such as hydroxyphenylglycine 1. This may be remedied using sodium succinate instead of sodium carbonate as base, but chemical yields are somewhat lower. Optically pure biaryl amino acids related to those found in the chloropeptins and vancomycin were synthesized by Suzuki coupling of 1 with indolylboronic acids 6-8 and with cyclic boronic acid 9.
