Protein post-translational modifications are involved in essentially all aspects of cellular signaling. Their dynamic nature and the difficulties in installing them using enzymatic approaches limits their direct study in human cells. Reported herein is the first synthesis, delivery and cellular study of a stable phosphoubiquitin probe. Our results compare Parkin's substrate preference during mitophagyviadirect visualization of a phosphorylated ubiquitin probe in the cellular environment.

Dimethylsulfoniopropionate (DMSP) is one of the most abundant sulfur metabolites in marine environments. The biosynthesis of DMSP and its degradation to dimethylsulfide are important links in the planetary sulfur cycle. Herein, the first complete description of a DMSP biosynthetic pathway is provided by the in vitro reconstitution of four enzymes from Streptomyces mobaraensis. The isolation of DMSP from S. mobaraensis cells grown at high salinity confirmed that this actinobacterium is indeed is a DMSP-producing organism. The described DMSP biosynthesis follows the same route as that previously described for angiosperm plants. Despite this chemical congruence, limited sequence similarity between plant and bacterial enzymes suggests that the two biosynthetic activities emerged by convergent evolution.

Curcuminoids have been reported to possess multiple bioactivities, such as antioxidant, anticancer and anti-inflammatory properties. Three novel series of curcuminoid derivatives (11a-h, 15a-h and 19a-d) with enhanced bioactivity have been synthesized. Among the synthesized compounds, 11b exhibited the most significant activity with an MIC of 0.5 μ M /mL against selected medically important Gram-positive cocci (S aureus and S viridans) and Gram-negative bacilli (E. coli and E. cloacae). The derivatives exhibited remarkable results in an antioxidant test with an IC50 2.4- to 9.3-folder smaller than curcuminoids. With respect to antiproliferative activity against Hep-G2, LX-2, SMMC7221 and MDA-MB-231, the derivatives exhibited an effect stronger than curcuminoids with an IC50 ranging from 0.18 to 4.25 μ M.
