The present invention relates to new antibody-drug conjugates (ADCs) targeting ROR1, active metabolites of such ADCs, methods for preparation of such ADCs, uses for such ADCs in treatment and/or prevention of illnesses, and uses for such ADCs in production of drugs for treatment and/or prevention of diseases, more specifically diseases associated with over-expression of ROR1, for example cancer. More specifically, the present invention relates to an antibody-drug conjugate comprising an antibody that binds to ROR1 or an antigen-binding fragment thereof, and a pharmaceutical composition comprising the same.

Antibody-drug conjugate comprising antibody against human ROR1 and use for the same

Substituted dihydroisoxazole derivatives useful as inhibitors of &#x3b2;-lactamases are provided. The invention further provides medical uses of substituted dihydroisoxazole derivatives, for example, as antibacterial agents.

Compositions and methods for inhibiting &#x3b2;-lactamase

Compositions and methods for inhibiting beta-lactamase

The present invention relates to novel cephalosporin derivatives represented by X, Y, L, R1, and R2 are as same as defined in the description of the invention. The present invention also relates to pharmaceutical antibiotic compositions comprising a novel celphalosporin derivative represented by Chemical Formula 1, a prodrug thereof, a hydrate thereof, a solvate thereof, an isomer thereof, or a pharmaceutically acceptable salt thereof as an effective ingredient. According to the present invention, novel cephalosporin derivatives, a prodrug thereof, a hydrate thereof, a solvate thereof, an isomer thereof, or a pharmaceutically acceptable salt thereof as an effective ingredient for the broad spectrum of antibiotic resistant, low toxicity, particularly in Gram-negative bacteria, which can be useful with strong antimicrobial activity.
