Betaine (trimethylglycine) 是许多食物中发现的天然化合物,也是能够维持正常 DNA 甲基化模式的特性甲基供体。它广泛存在于植物,动物,微生物和丰富的膳食来源中。它能够促进各种肠道微生物抵抗渗透变化,从而改善微生物发酵特性。它也能够作为渗透物,通过防止脱水和渗透失活来维持禽类的细胞水和离子平衡,从而提高禽类对热应激的能力。
8,9-Epoxy-3-isobutyryloxy-10-(2-methylbutanoyl)thymol is a chemical composition of essential oils from Telekia speciosa. It also shows marked antipro-liferative activity against human cancer cell lines in vitro.
Tos-PEG4-t-butyl ester (Tos-PEG4-Boc) is a PROTAC linker characterized by its PEG composition. This compound plays a crucial role in the synthesis of a range of PROTACs, including BI-3663, a highly selective PTK2 FAK PROTAC. It employs cereblon ligands to target E3 ligases for the degradation of PTK2, exhibiting potent inhibitory activity with an IC50 of 18 nM[1].
Boc-Pip-alkyne-Ph-COOH, a PROTAC linker characterized by its alkyl ether composition, plays a crucial role in synthesizing PROTACs including ARD-266. This compound demonstrates significant efficacy in promoting the degradation of androgen receptor (AR) protein across AR-positive prostate cancer cell lines such as LNCaP, VCaP, and 22Rv1, showcasing DC50 values ranging from 0.2-1 nM[1].
NH2-PEG5-C6-Cl (K-7) is a PROTAC linker characterized by its PEG composition. It can be utilized in the synthesis of various PROTACs, facilitating the degradation of intracellular molecules via autophagy[1].
Phthalimide-PEG4-MPDM-OH, a PROTAC linker with a PEGs composition, has applications in the synthesis of various PROTACs. These PROTACs consist of a linker connecting two distinct ligands: one binds to an E3 ubiquitin ligase, while the other binds to the target protein. By leveraging the intracellular ubiquitin-proteasome system, PROTACs selectively induce the degradation of target proteins [1].
S-(1-Hydroxy-2-methylpropan-2-yl) methanesulfonothioate, an ADC linker, is a glutathione cleavable compound used for the attachment of monoclonal antibodies (mAb) in antibody-drug conjugates (ADCs). It specifically refers to the Alkyl-Chain composition of the linker portion of these molecules [1].
