Actinobenzoquinoline and Actinophenanthrolines A—C, Unprecedented Alkaloids from a Marine Actinobacterium.
Sang Jip Nam,Christopher A. Kauffman,Paul R. Jensen,Curtis E. Moore,Arnold L. Rheingold,William Fenical +5 more
TL;DR: In this article, a marine actinomycete within the family Streptomycetaceae (our strain CNQ-149) has led to the isolation of the unprecedented alkaloids, actinobenzoquinoline (1) and actinophenanthrolines A-C (2-4).
Determination of process-related impurities in N-acetylglucosamine prepared by chemical and enzymatic methods: structural elucidation and quantification.
Yi Soo Kim,Sung Joong Lee,Jin Young Choi,Yun-Hi Kim,Kebede Taye Desta,Zhe Piao,Su Lim Choi,Sang Jip Nam,Kyung Yun Kang,A. M. Abd El-Aty,A. M. Abd El-Aty,Yong Chul Shin,Sung Chul Shin +12 more
TL;DR: It can be concluded that the enzymatic rather than the chemical method is more efficient for the synthesis of β-AG.
Previously Uncultured Marine Bacteria Linked to Novel Alkaloid Production
Eun Ju Choi,Sang Jip Nam,Lauren A. Paul,Deanna S. Beatty,Christopher A. Kauffman,Paul R. Jensen,William Fenical +6 more
TL;DR: The results demonstrate that relatively simple cultivation techniques can lead to the isolation of new bacterial taxa that are capable of the production of alkaloid secondary metabolites with antibacterial activities, and support continued investment in cultivation techniques as a method for natural product discovery.
A coumarin-based reversible two-photon fluorescence probe for imaging glutathione near N-methyl-D-aspartate (NMDA) receptors.
Nahyun Kwon,Chang Su Lim,Dayoung Lee,Gyeongju Ko,Jeongsun Ha,Moonyeon Cho,K.M.K. Swamy,Eunyoung Lee,Dong Joon Lee,Sang Jip Nam,Xin Zhou,Hwan Myung Kim,Ju-Yoon Yoon +12 more
TL;DR: Two-photon fluorescence microscopy allows probe 1 to successfully sense endogenous GSH in neuronal cells and hippocampal tissues with excitation at 750 nm and the addition of H2O2 and GSH induced a decrease and an increase in fluorescence emission.
Potent Inhibition of Monoamine Oxidase B by a Piloquinone from Marine-Derived Streptomyces sp. CNQ-027.
TL;DR: The results suggest that piloquinones from a microbial source could be potent reversible MAO inhibitors and may be useful lead compounds for developing MAO enzyme inhibitors to treat related disorders, such as depression, Parkinson's disease, and Alzheimer's disease.
