The present invention provides a Plexin-binding regulating agent containing a cyclic peptide having an Arg-Trp-Thr structure or a Leu-Ser-Trp structure or a pharmaceutically acceptable salt of the cyclic peptide.

A mixed mode affinity chromatography carrier includes a substrate, a hydrophilic polymer, an antibody-binding cyclic peptide, and a cation exchange group.

A method for the synthesis of daptomycin or a daptomycin analog is carried out on a resin to form a linear precursor followed by a serine ligation macrocyclization in solution. Daptomycin analogs can differ from daptomycin by substitution of amino acids residues and/or deletion or addition of amino acid residues. Daptomycin analogs can include a different fatty acid in the side arm of the daptomycin analog.

Cyclic peptide compounds are provided that can bind to one or more homologs of Hedghehog signaling proteins and block their interaction with the Patched receptor. These compounds are useful for suppressing Hedgehog-dependent stimulation of the Hedgehog pathway in cells and in living organisms. Methods for using the cyclic peptide compounds, and compositions comprising them, for treatment of cancers and other diseases which are characterized by aberrant Hedgehog-dependent activation of the Hedgehog pathway and/or which can benefit from chemical suppression of Hedgehog-dependent signaling are also disclosed.

The disclosure relates to methods of prophylactic and therapeutic treatments of a Pneumocystis infection (i.e., an infection caused by Pneumocystis jirovecii) in a subject by administering to the subject a compound of any of formulas (1)-(111) (e.g., a salt of Compound 1, or a neutral form thereof). The disclosure also relates to methods of inhibiting the replication of a Pneumocystis spp. The methods of the disclosure can be useful in immunocompromized subjects.

The present invention relates to antibodies, or antigen-binding fragments thereof, directed against human leukocyte antigen-G (HLA-G) protein and raised against an immunogenic peptide derived from the a3 domain of HLA-G protein. The invention further relates to the immunogenic peptide, and methods for producing said anti-HLA-G specific antibodies. A particular embodiment refers to the monoclonal antibody with the arbitrary designation 15E7 for which the sequence is provided. Also a anti-HLA-G single-chain antibody gene library was generated and six specific binders were identified from that library.
