TP\u2010A0019 led to the isolation of quinocidin (1), a cytotoxic antibiotic with an unusual 3,4\u2010dihydroquinolizinium ring. The structural assignment was made on the basis of high\u2010field NMR experiments and chemical synthesis. Comparison of the spectral properties of 1 with those of its synthetic counterparts revealed that 1 is a racemic mixture of two enantiomers, which showed similar cytotoxicity against HeLa\u2010S3 cells. Nucleophile\u2010trapping experiments demonstrated that 1 captured 2\u2010mercaptoethanol and N\u2010acetyl\u2010l\u2010cysteine by means of a Michael addition\u2010type reaction, but was inert toward 2\u2010aminoethanol and glycolic acid. Notably, the addition of 1 to thiols proceeded smoothly in neutral aqueous media at room temperature. In view of the thiol\u2010trapping ability and the unusual structure, 1 provides a unique scaffold for designing drug leads and protein\u2010labeling probes.", "subitem_description_type": "Abstract"}]}, "item_10_description_5": {"attribute_name": "\u5185\u5bb9\u8a18\u8ff0", "attribute_value_mlt": [{"subitem_description": "\u30d5\u30a1\u30a4\u30eb\u516c\u958b\uff1a2018-12-19", "subitem_description_type": "Other"}]}, "item_10_publisher_32": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "Wiley"}]}, "item_10_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "https://doi.org/10.1002/chem.201704729", "subitem_relation_type_select": "DOI"}}]}, "item_10_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": " \t\"This is the peer reviewed version of the following article: [Y.
