Fig. 2From: Chili pepper extracts, capsaicin, and dihydrocapsaicin as potential anticancer agents targeting topoisomerasesDecatenation assay for topoisomerase II. Topoisomerase II decatenation assay was carried out using kinetoplast DNA (kDNA, 200 ng) in human topoisomerase IIa (hTop IIa, 1.5 U) enzyme, in 1/10 of stock solutions (3 μL from extracts, capsaicin 0.5 mg/mL and 1.0 mg/mL). Extracts: HR – Habanero Red; HMR – Habanero Maya Red; TMS – Trinidad Moruga Scorpion; J – Jalapeno; SP – Serrano pepper; HRS – Habanero Red Savina; BJ – Bhut Jolokia; JR – Jamaica Rosso (final concentration 1/10 of stock solution); CAP 1 – capsaicin (final concentration 0.05 mg/mL); CAP 2 – capsaicin (final concentration 0.1 mg/mL); DHK – dihydrocapsaicin (final concentration 0.05 mg/mL); K1 – kDNA; K2 – kDNA + Topo II (1.5 U) + EtOHBack to article page
