The ability to selectively degrade proteins with bifunctional small molecules has the potential to fundamentally alter therapy in a variety of diseases. However, the relatively large size of these chimeric molecules often results in challenging physico-chemical properties (e. g., low aqueous solubility) and poor pharmacokinetics which may complicate their in vivo applications. We recently discovered an exquisitely potent chimeric BET degrader (GNE-987) which exhibited picomolar cell potencies but also demonstrated low in vivo exposures. In an effort to improve the pharmacokinetic properties of this molecule, we discovered the first degrader-antibody conjugate by attaching GNE-987 to an anti-CLL1 antibody via a novel linker. A single IV dose of the conjugate afforded sustained in vivo exposures that resulted in antigen-specific tumor regressions. Enhancement of a chimeric protein degrader with poor in vivo properties through antibody conjugation thereby expands the utility of directed protein degradation as both a biological tool and a therapeutic possibility.

Page/Page column 127; 152; 153, (2017/05/02)
The invention relates generally to disulfide drug conjugates wherein a linker comprising a sulfur-bearing carbon atom substituted with at least one hydrocarbyl or substituted hydrocarbyl is conjugated by a disulfide bond to a cysteine sulfur atom of a targeting carrier, and wherein the linker is further conjugated to a drug moiety. The invention further relates to activated linker-drug conjugates suitable for conjugation to a targeting carrier by a disulfide bond. The invention further relates to methods for preparing hindered disulfide drug conjugates.

Page/Page column 42, (2008/06/13)
The present invention describes novel nitrosated and/or nitrosylated prostaglandins, and novel compositions comprising at least one nitrosated and/or nitrosylated prostaglandin, and, optionally, at least one compound that donates, transfers or releases nitric oxide, elevates endogenous levels of endothelium-derived relaxing factor, stimulates endogenous synthesis of nitric oxide or is a substrate for nitric oxide synthase, and/or at least one vasoactive agent. The present invention also provides novel compositions comprising at least one prostaglandin and at least one S-nitrosothiol compound, and, optionally, at least one vasoactive agent. The prostaglandin is preferably a prostaglandin E1 compound, more preferably alprostadil, and the S-nitrosothiol compound is preferably S-nitrosoglutathione. The present invention also provides methods for treating or preventing sexual dysfunctions in males and females, for enhancing sexual responses in males and females, and for treating or preventing cerebrovascular disorders, cardiovascular disorders, benign prostatic hyperplasia (BPH), glaucoma, peptic ulcers or for inducing abortions. The compounds and/or compositions of the present invention can also be provided in the form of a pharmaceutical kit.
