Possibilities for the prevention of cancer, particularly in relation to the food supply, are considered. It is suggested that the growing realization that cancer may be induced by more than one mechanism combined with a present lack of knowledge of the nature and level of naturally-occurring carcinogens in food crops, makes successful prevention in humans exceedingly difficult.

Department of Chemistry and Biochemistry, University of North Carolina at Greensboro, Greensboro, NC 27402, United States.

BURP domain peptide cyclases, or BpCs (an abbreviation we recommend in this opinion), are an emerging class of copper enzymes which catalyze the oxidative macrocyclization of peptides in plants. A close examination of their novel protein fold, along with the unique dicopper active site that meticulously controls crosslinking within peptides, highlights how nature exploits intricate mechanistic strategies to achieve diverse functionalities. Here, we summarize recent discoveries regarding the sequence, structure, function, and proposed chemistry of BpCs.

ConspectusIn the search for efficient and selective electrocatalysts capable of converting greenhouse gases to value-added products, enzymes found in naturally existing bacteria provide the basis for most approaches toward electrocatalyst design. Ni,Fe-carbon monoxide dehydrogenase (Ni,Fe-CODH) is one such enzyme, with a nickel-iron-sulfur cluster named the C-cluster, where CO binds and is converted to CO at high rates near the thermodynamic potential. In this Account, we divide the enzyme's catalytic contributions into three categories based on location and function.

Recently, nickel catalysts have garnered considerable attention for their efficacy and versatility in asymmetric catalysis, attributed to their distinctive properties. However, the use of cost-effective and sustainable divalent nickel catalysts in C-H activation/asymmetric alkene insertion poses significant challenges due to the intricate control of stereochemistry in the transformation of the tetracoordinate C-Ni(II) intermediate. Herein, we report a Ni(II)-catalyzed enantioselective C-H/N-H annulation with oxabicyclic alkenes.

Target cyclooxygenase 2 (COX-2) and 5-lipoxygenase (5-LOX) inhibitors; 5-([2,5-Dihydroxybenzyl]amino)salicylamides (Compounds 1-11) were examined for potential anticancer activity, with a trial to assess the underlying possible mechanisms. Compounds were assessed at a single dose against 60 cancer cell lines panel and those with the highest activity were tested in the five-dose assay. COMPARE analysis was conducted to explore potential mechanisms underlying their biological activity.
