Published: August 2013

Five new anthranilic acid derivatives, penipacids A-E (1-5), together with one known analogue (6), which was previously synthesized, were characterized from the ethyl acetate extract of the marine sediment-derived fungus Penicillium paneum SD-44. Their structures were elucidated mainly by extensive NMR spectroscopic and mass spectrometric analysis. The cytotoxicity and antimicrobial activity of the isolated compounds were evaluated. Compounds 1, and 5 exhibited inhibitory activity against human colon cancer RKO cell line, while compound 6 displayed cytotoxic activity against Hela cell line.

Background: To construct a prediction model consisting of metabolites and proteins in peripheral blood plasma to predict whether patients with unresectable stage III and IV non-small cell lung cancer can benefit from immunotherapy before it is administered.

Methods: Peripheral blood plasma was collected from unresectable stage III and IV non-small cell lung cancer patients who were negative for driver mutations before receiving immunotherapy. Then we classified samples according to the follow-up results after two courses of immunotherapy and non-targeted metabolomics and proteomics analyses were performed to select different metabolites and proteins.

Opioid drugs such as morphine are frequently preferred drugs for severe pain in cancer and chronic diseases, but long-term use causes opioid tolerance. The mechanism of tolerance to opioids is quite complex and not fully understood. Our aim in this study was to investigate the effects of TRPM2 cation channel antagonists N-(p-amylcinnamoyl) anthranilic acid (ACA) and 2-aminoethoxydiphenyl borate (2-APB) on morphine analgesia and tolerance in rats.

Transition, post-transition and rare earth metal complexes supported by (O,N)- and (N,N)-type ligands dominate organometallic photochemistry. However, despite a vast number of aminobenzoate metal complexes having been reported, and aluminium being globally abundant, alkylaluminium anthranilates have not yet been considered as effective luminophores. Herein, using a family of commercially available ligands composed of anthranilic acid (anth-H) and its N-substituted derivatives, we report the isolation and characterisation of a series of unique tetrameric chiral-at-metal alkylaluminium anthranilates, [(R'-anth)AlR].

Margalefidinium polykrikoides blooms inflict significant economic losses on the aquaculture industry. Utilizing algicidal bacteria to mitigate harmful algal blooms (HABs) has emerged as an environment-friendly approach. Despite numerous reports on algicidal bacteria, few studies have thoroughly elucidated their mechanisms against M.
