The present invention relates to biscarbodiimides, thiourea derivatives, urea derivatives, and cross-linked hyaluronan derivatives having at least one intramolecular disulfide bond, and methods of preparation thereof. The invention also includes thiolated hyaluronan derivatives and salts thereof having at least one pendant thiol group or a modified pendant thiol group, and methods of preparation thereof. An example of a modified pendant thiol group is a sulfhydryl group linked to a small molecule such as a bioactive agent, for example a drug or pharmaceutically active moiety. A hyaluronan derivative having a sulfhydryl group linked to a pharmaceutically active moiety is useful as a sustained or controlled release drug delivery vehicle. Compositions containing the hyaluronan derivatives of the invention can reversibly viscosify in vivo or in vitro, in response to mild changes in condition, and are thus useful in ophthalmic surgery and in tissue engineering.

Methods are described for modifying the isoelectric point of an antibody while retaining its antigen-binding activity, comprising modifying the charge of at least one exposable amino acid residue on the surface of the complementarity determining region (CDR). The disclosure also provides methods for purifying multispecific antibodies, comprising modifying isoelectric point, and methods for improving the plasma pharmacokinetics of antibodies with a modified isoelectric point. The disclosure further provides antibodies with a modified isoelectric point, pharmaceutical compositions comprising the antibodies as an active ingredient, and methods for producing the antibodies and compositions.

A concentrated inhalable formulation of an antibiotic drug such as ciprofloxacin is disclosed. The antibiotic is formulated with sodium acetate and liposome which incorporate antibiotic. The formulation is aerosolized and inhaled for treatment of respiratory tract infections and other medical conditions.

The present invention encompasses novel antibodies and fragments thereof which immunospecifically bind to one or more RSV antigens and compositions comprising said antibodies and antibody fragments. The present invention encompasses methods preventing respiratory syncytial virus (RSV) infection in a human, comprising administering to said human a prophylactically effective amount of one or more antibodies or fragments thereof that immunospecifically bind to one or more RSV antigens, wherein a certain serum titer of said antibodies or antibody fragments is achieved in said human subject. The present invention also encompasses methods for treating or ameliorating symptoms associated with a RSV infection in a human, comprising administering to said human a therapeutically effective amount of one or more antibodies or fragments thereof that immunospecifically bind to one or more RSV antigens, wherein a certain serum titer of said antibodies or antibody fragments is achieved in said human subject. The present invention further encompasses compositions comprising antibodies or fragments thereof that immunospecifically bind to a RSV antigen, and methods using said compositions for detection or diagnosis of a RSV infection.

Methods for formulating immediate and sustained release anti-infectives and delivery of such for treatment of respiratory tract infections and other medical conditions, and devices and formulations used in connection with such are described.

The invention relates to the field of medicaments, in particular to an integrin blocking agent HM-3 which has the function of inhibiting tumor angiogenesis, integrin affinity and a bonding capacity and application thereof. The blocking agent is a polypeptide modified with polyethylene glycol, and the modified integrin blocking agent polypeptide can be applied to treatment of solid tumors. During application of the integrin blocking agent to preparation of a tumor treatment medicament, the sequence and structure of the integrin blocking agent is mPEG-SC20k-Ile-Val-Arg-Arg-Ala-Asp-Arg-Ala-Ala-Val-Pro-Gly-Gly-Gly-Gly-Arg-Gly-Asp. The integrin blocking agent polypeptide designed in the invention is scientific, reasonable, practical and effective, can be used for preparing a treatment medicament for treating human solid tumors, and has remarkable social value and market value; and the treatment spectrum of the integrin blocking agent is expanded greatly, and novel thought and prospect are provided for future development of medicaments.
