Frenolicins C-G, pyranonaphthoquinones from Streptomyces sp. RM-4-15.
Wang X, Shaaban KA, Elshahawi SI, Ponomareva LV, Sunkara M, Zhang Y, Copley GC, Hower JC, Morris AJ, Kharel MK, Thorson JS. Wang X, et al. Among authors: copley gc. J Nat Prod. 2013 Aug 23;76(8):1441-7. doi: 10.1021/np400231r. Epub 2013 Aug 14. J Nat Prod. 2013. PMID: 23944931 Free PMC article.
An additional new analogue, frenolicin G (5), along with two known compounds, deoxyfrenolicin (9) and UCF 13 (10), were isolated from the fermentation supplied with 18 mg/L of scandium chloride, the first example, to the best of our knowledge, wherein scandium chloride sup …

Intramolecular excimer formation for covalently linked boron dipyrromethene dyes.
Alamiry MA, Benniston AC, Copley G, Harriman A, Howgego D. Alamiry MA, et al. Among authors: copley g. J Phys Chem A. 2011 Nov 10;115(44):12111-9. doi: 10.1021/jp2070419. Epub 2011 Oct 14. J Phys Chem A. 2011. PMID: 21951157
Time-resolved fluorescence studies show dual-exponential decay kinetics in each case, while temperature-dependent emission studies reveal reversible coupling between monomer and lower-energy excimer states. The latter is weakly fluorescent, at best, and is seen clearly onl …
