    Abstract: The present invention relates to antibody-drug conjugates (ADCs) wherein a plurality of active agents are conjugated to an antibody through at least one branched linker. The branched linker may comprise a branching unit, and two active agents are coupled to the branching unit through a secondary linker and the branching unit is coupled to the antibody by a primary linker. The active agents may be the same or different. In certain such embodiments, two or more such branched linkers are conjugated to the antibody, e.g., 2-4 branched linkers, which may each be coupled to a different C-terminal cysteine of a heavy or light chain of the antibody. The branched linker may comprise one active agent coupled to the branching unit by a first branch and a second branch that comprises a polyethylene glycol moiety coupled to the branching unit. In certain such embodiments, two or more such branched linkers are conjugated to the antibody, e.g.

  • Publication number: 20240083410
    Abstract: Disclosed are a hybrid electric vehicle and a method for controlling an engine speed of a hybrid electric vehicle. In particular, the method includes: determining, when an engine on one end and a first motor are directly connected and while driving in a state where an engine clutch is connected and a second motor is connected to the other end, a compensation value based on the difference in the rotational speed of the engine and the second motor when a control entry is caused, which induces the rotational speed mismatch of the engine and the second motor; and compensating an output torque of the first motor based on the compensation value.
