The conversion of citrulline to arginine in kidney [PDF]
, 1941 Glycocyamine is formed in the kidney by the transfer of the amidine group of arginine to the nitrogen atom of glycine. In the study of this reaction it was observed that glycocyamine was also formed from citrulline and glycine.

ChemBioChem, Accepted Article.2‐oxoglutarate (2OG)‐dependent non‐heme iron (NHFe) enzymes constitute a family of enzymes that use 2OG and oxygen to catalyze the hydroxylation of unactivated C(sp3)–H bonds. These enzymes are of biological importance and therapeutic interest due to their role in regulating various cellular processes. Herein, we have rationally designed two classes of

A Bis‐Thiosemicarbazone Pd(II) SiO2 Nanoparticle Conjugate for CC Coupling Catalysis
European Journal of Inorganic Chemistry, EarlyView.The thiosemicarbazone (TSC) Pd complex–SiO2 nanoparticle conjugate [PdL]–APTES–SiO2 (APTES = (3‐aminopropyl)triethoxysilane) was synthesized through covalent binding of the pentadentate bis(N4‐(2‐ethylphenyl)) 2,6‐diacetyl‐pyridine TSC onto monodispersed SiO2, followed by coordination of Pd(II) and used as precatalysts in Suzuki–Miyaura‐type cross ...

Pyruvate-Associated Acid Resistance in Bacteria [PDF]
Applied and Environmental Microbiology, 2014 ABSTRACT Glucose confers acid resistance on exponentially growing bacteria by repressing formation of the cyclic AMP (cAMP)-cAMP receptor protein (CRP) complex and consequently activating acid resistance genes. Therefore, in a glucose-rich growth environment, bacteria are capable of resisting acidic stresses due to low levels of cAMP-CRP ...

Toward the Synthesis of 3,3‐Difluoro Deaminated Sialic Acid (C3DFKDN)
European Journal of Organic Chemistry, EarlyView.The synthesis of protected C3‐difluoro KDN (C3DFKDN), an unnatural derivative of the sialic acid member, KDN, and key building block for KDN‐based chemical probes, is reported. Its 12‐step synthetic route starts from commercially available methyl d‐mannopyranoside and key steps include a Reformatsky reaction with ethyl bromodifluoroacetate, alkylation ...
