Trifunctional reagents for substrate-protein conjugation: Application to pyrrolizidine alkaloid analogues
Kurth,Milco,Miller
, p. 1407 - 1416 (1992)
We report the syntheses of two pyrrolizidine alkaloid (PA) analogues (1 and 2) which exploit the novel substrate-protein coupling reagents 4 and 5. Analogues 1 and 2 incorporate the targeted PA substructural unit (i.e., a macrocyclic diester of retronecine), possess a handle for protein conjugation, and potentially maintain the conformational integrity of macrocyclic PAs.
Design, synthesis and evaluation of novel bifunctional tetrahydroxamate chelators for PET imaging of89Zr-labeled antibodies
Rousseau, Julie,Zhang, Zhengxing,Dias, Gemma M.,Zhang, Chengcheng,Colpo, Nadine,Bénard, Fran?ois,Lin, Kuo-Shyan
, p. 708 - 712 (2017)
Two compact and symmetrical bifunctional tetrahydroxamate chelators, 1 and 2, were synthesized and evaluated for labeling antibodies with89Zr for imaging with positron emission tomography. Using 2,2′-iminodiacetamide as the backbone, four hydro
Selective Extraction and Complexation Studies for Thorium(IV) with Bis-triamide Extractants: Synthesis, Solvent Extraction, EXAFS, and DFT
Kang, Jinyang,Wu, Rulei,Li, Long,Hu, Haiyang,Fan, Yu,Jin, Yongdong,Huang, Chao,Chen, Jing,Xu, Chao,Xia, Chuanqin
, p. 14212 - 14220 (2021/09/20)
Three octyl-extended bis-triamide extractants (L1-L3) were designed and synthesized for the selective solvent extraction of Th(IV) over U(VI) in a kerosene-HNO3system. L1 and L2 exhibited good extraction property and selectivity toward Th(IV) o

The invention discloses a substance related with tophatib and a preparation method and application thereof. The substance is named as N,N'-diacetyl{(3R,4R)-4-methyl-3-[methyl(7H-pyrrole[2,3-D]pyrimidine-4-yl)amine]piperidine-1-yl}imine. The impurity is characterized in that the generation level is lower in the condensation reaction process; however, the impurity has the uniform main functional groups with the tophatib, the cleaning effect is limited in the subsequent salting and refining process, and the influence to the qualities of crude drug and finished product of tophatib is larger; by detecting the existence of the impurity, the qualities of the raw material and preparation of the tophatib can be effectively determined.
