Problems solved by technology

IDPs are challenging targets because they exist as ensembles of structures, which can make standard rational drug design methods difficult because they require knowledge of the three-dimensional structure of the protein to be administered
Despite understanding their association with numerous diseases, limited attention has been paid to developing strategies to therapeutically target IDPs and proteins with IDRs (Heller, G.T. et al., Cell MolLife Sci, 2017, Vol. 74 No. 17: No. 3225 -3243), and are generally considered "non-druggable" (Dang, C.V. et al., Nat Rev Cancer, 2017, Vol. 17, No. 8: pp. 502-508)

preparation example Construction

[0189] For the preparation of solutions or suspensions, for example water, especially sterile water, or physiologically acceptable organic solvents such as alcohols (ethanol, propanol, isopropanol, 1,2-propylene glycol, polyethylene glycol, Glycols and their derivatives, fatty alcohols, partial esters of glycerol), oils (e.g., peanut oil, olive oil, sesame oil, almond oil, sunflower oil, soybean oil, castor oil, cowshoe oil), paraffin, dimethylmethylene Sulfone, triglyceride, etc.

[0190] In the case of liquid dosage forms such as potable solutions, the following substances can be used as stabilizers or solubilizers: lower aliphatic monovalent and polyvalent alcohols with 2 to 4 carbon atoms, such as ethanol, n-propanol, glycerol, Polyethylene glycols with a molecular weight between 200-600 (for example, 1%-40% in water), diethylene glycol monoethyl ether, 1,2-propanediol, organic amides, such as aliphatic C1-C6-carboxylic acids and ammonia or amides of primary, secondary or...

Embodiment

[0346] Having now generally described the embodiments of the disclosure, the following examples describe some other embodiments of the disclosure. While embodiments of the disclosure are described in conjunction with the following examples and corresponding text and figures, it is not intended to limit the aspects of the disclosure to this description. On the contrary, the intention is to cover all alternatives, modifications, and equivalents as included within the spirit and scope of embodiments of the present disclosure.

[0347] method

[0348] protein preparation

[0349] After subcloning into pET28a (Novagen) using established procedures, the p27 construct containing an N-terminal 6xHis affinity tag was expressed in E. coli (BL21 / DE3) (Lacy, E.R. et al., Nat Struct Mol Biol, 2004, Volume 11, Chapter 4: pp. 358-364). This includes p27-KID (residues 22-105 of human p27) and p27-D2 (residues 58-105 of human p27) and the following mutants: W60A, W76A, W60A-W76A. Isotopi...

Abstract

Various compounds and pharmaceutically acceptable salts thereof are provided capable of binding cyclin-dependent kinase inhibitor 1B. The compounds can have a structure according to Formula I or Formula II as detailed herein. The compounds can include SJ747, SJ749, SJ755, SJ757. Pharmaceutical formulations containing the compounds or pharmaceutically acceptable salts are also provided along with methods of use thereof. The formulations and methods can be useful for treating cancer. In some aspects, the cancer is associated with a mislocalization of the intrinsically disordered protein p27. In some aspects, the cancer is resistant to an anticancer therapy. The pharmaceutical formulation can therefore include a second active agent and / or can be given in combination with a second active agent such as a cancer therapeutic. In various aspects, methods of promoting reentry into the cell division cycle in a subject in need thereof using compounds and formulations described herein are also provided.
