##STR00001##

or a pharmaceutically acceptable salt, solvate, enantiomer, stereoisomer, or isotopic derivative thereof, which contains, on one end, a cereblon E3 ubiquitin ligase that binds to the E3 ubiquitin ligase and, on the other end, a moiety that binds the target protein, Interleukin-1 Receptor-Associated Kinase 4 (IRAK-4), such that the target protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of target protein. The bifunctional compounds of the present disclosure present disclosure exhibit a broad range of pharmacological activities associated with degradation/inhibition of target protein. Diseases or disorders that result from cellular signaling mediated by the target protein are treated or prevented with bifunctional compounds and compositions of the present disclosure.

Antibody conjugates with camptothecin compounds are described, with methods of use and preparations.

Described herein is a bi-functional compound for removing macrophage migration inhibitory factor (MIF) or immunoglobin G (IgG). Further described herein is a pharmaceutical composition which comprise these bi-functional compounds. Further described herein is a method for treating disease states and/or conditions with the compounds or the composition. The disease states and/or conditions are mediated through MIF/IgG or where MIF/IgG is a contributing factor to the development and perpetuation of diseases and/or conditions, such as autoimmune diseases and cancer, among others.

Excessive deposition of extracellular matrix is a hallmark of Idiopathic pulmonary fibrosis (IPF), it is advantageous to target the cells and the mechanisms associated with this process. By targeting myofibroblasts (specialized contractile fibroblasts) that are key for the development of IPF with drugs conjugated with fibroblast activation protein (FAP). this technology helps minimize the production of extracellular matrix in the lungs and provides a new treatment option for patients diagnosed with IPF.

According to the dye molecule, a triazole ring is introduced to the design of a molecular structure, and the electronic absorption and transmission capability among D-pi-A dye molecules are greatly improved by substituting donors with different carbon chain lengths and receptors with triple bonds at the periphery, so that a novel triazole dye with high efficiency is obtained. The preparation method of the compound comprises: click chemical reaction, detrimethylsilyl reaction, Sonogashira coupling reaction and the like; and the prepared dye molecule can be applied to a dye-sensitive solar cell and can show favorable photoelectric conversion property so as to have wide application prospects on the aspects of energy development and utilization. In addition, the material also has liquid crystal property under a certain condition so as to also have a huge potential on the aspect of application to photoelectric devices.

This disclosure relates to heterobifunctional compounds (e.g., bi-functional small molecule compounds), compositions comprising one or more of the heterobifunctional compounds, and to methods of use the heterobifunctional compounds for the treatment of certain disease in a subject in need thereof. The disclosure also relates to methods for identifying such heterobifunctional compounds.

A combination therapy involving different therapeutic molecules can enhance and improve the therapeutic potentials. An effective therapeutic strategy conjugates silica (SiO.sub.2) nanoparticles with, e.g., 3-glycidyloxypropyl, trimethoxysilane and azoles, e.g., 1,2,4-triazole (Tri), 3-aminotriazole (ATri), 5-aminetetrazole (Atet), imidazole (Imi). These exemplary materials—classified as SiO.sub.2-3GPS-Tri (Conj. 1), SiO.sub.2-3GPS-Atri (Conj. 2), SiO.sub.2-3GPS-Atet (Conj. 3), SiO.sub.2-3GPS-Btri (Conj. 4), and SiO.sub.2-3GPS-Imi (Conj. 5)—can amplify targeting of therepeutics for human colorectal carcinoma cells (HCT-116), enhancing anti-cancer effects.

Bifunctional chimeric heterocyclic compounds of formula (I) is effective for targeted degradation of androgen receptors and use thereof. The compound of formula (I) also has an isotopic compound, an optical isomer, a tautomer, pharmacologically acceptable salt, a prodrug thereof, or a solvate. In formula (I), ARB is an androgen receptor recognition/binding part, L is a link part, and U is a ubiquitin protease recognition/binding part; and the three parts are connected by means of chemical bonds.
