BACKGROUND
Acute myeloid leukemia (AML) is the most common hematological malignancy in adults, characterized by distorted proliferation and development of myeloid cells and their precursors in the bone marrow. Nitidine chloride, a naturally occurring alkaloid, has been identified to possess
The indenoisoquinoline analogue 9 of nitidine (1) has been prepared and found to possess significant anticancer activity against L1210 lymphoid leukemia, P388 lymphocytic leukemia, and B16 melanocarcinoma. Analogue 14, which lacks the B ring of nitidine (1), has also been synthesized. Compound 14
BACKGROUND
We have shown previously that nitidine chloride (NC) induces apoptosis via inhibition of signal transducer and activator of transcription 3 (STAT3). However, its downstream molecules are not fully understood yet. Here, we report that NC as STAT3 inhibitor downregulates myeloid cell
The proto-oncogene c-Myc plays critical roles in human malignancies including chronic myeloid leukemia (CML), suggesting that the discovery of specific agents targeting c-Myc would be extremely valuable for CML treatment. Nitidine Chloride (NC), a natural bioactive alkaloid, is suggested to possess
Fagaronine and nitidine are natural benzo[c] phenanthridinium alkaloids, which display antileukemic activity. Both act as topoisomerase I and topoisomerase II inhibitors. The objective of the present study was to prepare noncharged isosters of these compounds, with replacement of the aromatic A ring
Different 7,8,9,10-tetrahydrobenzo[c]phenanthridin-6(5H)-ones (10a-e) were prepared by using a one-pot procedure which includes the preparation of various 6- and 7-alkoxy-1-naphthylisocyanates from 1-naphthylamines and triphosgene, followed by addition of 1-N-morpholino-1-cyclohexenes, and
Fagara tessmannii Engl. is an African medicinal plant used in Cameroonian traditional medicine to treat various types of cancers.AIM OF THE STUDY
This work was designed to determine the cytotoxicity of the crude extract (FTB), fractions (FTBa-d) and
The known alkaloids nitidine chloride [1] and 6-oxynitidine [2] and a new compound 6-methoxy-5,6-dihydronitidine [3] have been isolated from Fagara macrophylla. Compound 3 was the major product and was shown to be an artifact. The alkaloids 1 and 3 have been interconverted by treatment of 1 under
