Correction: Chrysomycins A–C, antileukemic naphthocoumarins from Streptomyces sporoverrucosus

Abstract

Correction for ‘Chrysomycins A–C, antileukemic naphthocoumarins from Streptomyces sporoverrucosus’ by Shreyans K. Jain et al., RSC Adv., 2013, 3, 21046–21053, https://doi.org/10.1039/c3ra42884b.

The authors regret that incorrect versions of Fig. 6 and Fig. 7 were included in the original article. The correct versions of Fig. 6 and 7 are presented below.

Fig. 6. Influence of compounds 1–3 on the nuclear morphology of human leukaemia HL-60 cells. The cells were treated with 1, 3 and 5 μM concentrations of these compounds for 24 h and stained with Hoechst 33258 for 40 min. The altered nuclear morphology and apoptotic bodies indicated by white arrows are seen in treated cells while the nuclei of the untreated cells were round and intact.

Fig. 7. Phase contrast microscopy of compound-treated leukaemia HL-60 cells. Cells were treated with compounds 1–3 at 1, 3 and 5 μM for 24 h and visualized using a phase contrast microscope (Olympus1X72). The morphology of treated cells altered in a concentration-dependent manner, while the untreated cells remained healthy.

The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
