Thanzeel, F. Yushra,Wolf, Christian
, p. 18960 - 18965 (2021)
We report chemoselective and modular peptide bioconjugation using stoichiometric amounts of 4-halocoumarin and arylsulfonate agents that undergo metal-free C(sp2)-heteroatom bond formation at micromolar concentrations. The underlyingipso-substi
A General Supramolecular Approach to Regulate Protein Functions by Cucurbit[7]uril and Unnatural Amino Acid Recognition
Cao, Wenbing,Qin, Xuewen,Wang, Yong,Dai, Zhen,Dai, Xianyin,Wang, Haoyu,Xuan, Weimin,Zhang, Yingming,Liu, Yu,Liu, Tao
, p. 11196 - 11200 (2021)
Regulation of specific protein function is of great importance for both research and therapeutic development. Many small or large molecules have been developed to control specific protein function, but there is a lack of a universal approach to regulate t
Metal complexes with biologically important ligands, CLXI [1]. Halfsandwich complexes with tert-leucine, dipeptides, pentaglycine and glutathione
Hoffmüller, Winfried,Dialer, Harald,Beck, Wolfgang
, p. 1278 - 1286 (2005)
Reactions of L-tert-Leucine (tert-butylglycine), tert-leucine methyl ester, GlyValOMe, and Leu-AlaOMe with the chloro-bridged complexes [Cp*IrCl 2]2, [(p-cymene)RuCl2]2 or [(C 6Me6)RuCl2]2 in the presence of NaOMe give the complexes [Cp*Ir(Cl)NH2CH(R)CO2] (1), [(p-cymene)Ru(Cl)-NH2CH(R)CO2] (2), Cp*Ir(Cl 2)[NH2CH(R)CO2Me] (5), {(C6Me 6)Ru(Cl)[NH2CH2CONHCH(R)-CO2Me]} +Cl- (6), [Cp*Ir(Cl)NH2CH 2CONCH(R)CO2Me] (7), [Cp*Ir(Cl)NH 2CH(CH2CHMe2)-CONCH(R)CO2Me)] (8), and Cp*Ir(Cl2)[NH2CH2CONHCH(R)CO 2Me) (9). With pentaglycine the complexes [Cp*Ir(Cl 2)(pentaglycinate+Na+)] (10) and [(C 6Me6)Ru(pentaglycineOMe-H+)] (11) could be isolated. Coordination of one equivalent of the S-protected tripeptide glutathione to [Cp*Ir(Cl)] and to [(C6Me6)Ru(Cl)] was observed. Some in situ prepared (p-cymene)Ru complexes with deprotonated dipeptide esters were tested as catalysts and the complex [(p-cymene)Ru(Cl) (NH2CH(CHMeEt)NCH (CHMe2)CO2tert-Bu)] gave a yield of 73% and moderate entantiomeric excess (36% ee) in the transfer hydrogenation of acetophenone to 2-propanol.

Yamamoto, Kohji,Usuda, Kazuhiro,Kakuta, Yoshimitsu,Kimura, Makoto,Higashiura, Akifumi,Nakagawa, Atsushi,Aso, Yoichi,Suzuki, Mamoru
, p. 1469 - 1474 (2012)
Background: Glutathione transferase (GST) catalyzes glutathione conjugation, a major detoxification pathway for xenobiotics and endogenous substances. Here, we determined the crystal structure of a Delta-class GST from Bombyx mori (bmGSTD) to examine its
Contributions of Thiolate "Desolvation" to Catalysis by Glutathione S-Transferase Isozymes 1-1 and 2-2: Evidence from Kinetic Solvent Isotope Effects
Huskey, Su-Er W.,Huskey, W. Phillip,Lu, Anthony Y. H.
, p. 2283 - 2290 (1991)
Kinetic solvent isotope effects on the reaction of glutathione with 1-chloro-2,4-dinitrobenzene catalyzed by rat liver glutathione S-transferase isozymes 1-1 and 2-2 (as expressed in Escherichia coli) have been measured. At pH (and pD) = 8.0, the isotope
