摘要: Bioassay-guided fractionation of Haplophyllum canaliculatum Boiss. (Rutaceae) extract resulted in isolation five quinoline alkaloids: 7-isopentenyloxy-gamma-fagarine, atanine, skimmianine, flindersine and perfamine. This is the first these compounds from this endemic species. The antitumor activity isolates was evaluated against RAJI, Jurkat, KG-1a, HEP-2, MCF-7, HL-60 HL-60/MX1 tumor cell lines. highest cytotoxic effect observed on acute lymphoblastic leukemia 7-Isopentenyloxy-gamma-fagarine, skimmianine exhibited very high cytotoxicity RAJI line with IC(50) values 1.5, 14.5, 15.6 14.9 microg/mL, respectively atanine Jurkat 3.6, 9.3 11.5 respectively. 7-Isopentenyloxy-gamma-fagarine also highly MCF-7 (IC(50) = 15.5 microg/mL), while perfamine showed moderate to low cells. All alkaloids had KG-1a HEP-2. Investigation toxic potential a significantly higher HL-60/MX1, multidrug-resistant line, compared control etoposide (p < 0.05). In all experiments, peripheral blood mononuclear cells (PBMC) were used as for normal hematopoietic Flow cytometry analysis arrest cycle progression at sub-G1 phase lines dose-dependent manner. According computational analyses, similar trend could be indicative fact that may act through parallel mechanisms.
