Five new 4-alkyl-5,7-dihydroxycoumarins, Mesuaferol G-K (1-5), together with four known 4-alkyl-5,7-dihydroxycoumarins (6-9) were isolated from the methanol extraction of the flowering buds of Mesua ferrea by flash extraction. Their structures were established on the basis of extensive analyses of

Artemisinin is an endoperoxide sesquiterpene lactone, and has been proven to be very effective in treating drug resistant cases of malaria, cancer, etc. The compound is obtained from Artemisia species. In the current study, the effects of vegetative and flowering stages on artemisinin production

The essential oil extracted by hydrodistillation from the flowering twigs of Stevia rebaudiana Bertoni (Asteraceae) was fractioned by chromatography. Forty-three constituents were characterized with the help of GC, GC-MS and other spectroscopic techniques. The essential oil was found to be a complex

Brassica incana Ten. is an edible plant belonging to the Brassicaceae family. In this work, the phenolic composition and the antioxidant and cytotoxic properties of the hydroalcoholic extracts obtained from the leaves and the flowering tops of B. incana grown wild in Sicily (Italy)

Paeonia suffruticosa is an ornamental, edible, and medicinal plant. The ethanolic extracts of P. suffruticosa bud and flower were examined for their antioxidant, anti-photoaging, and phytochemical properties prior to chemometric analysis. The results showed that the bud

BACKGROUND tRNase Z removes the 3'-trailer sequences from precursor tRNAs, which is an essential step preceding the addition of the CCA sequence. tRNase Z exists in the short (tRNase ZS) and long (tRNase ZL) forms. Based on the sequence characteristics, they can be divided into two major types:

Most anticancer drugs are teratogens, merely because they target vital cellular functions. Conversely, some plants produce agents that intentionally target embryonic signaling pathways, precisely to cause birth defects if pregnant animals eat such plants. Cyclopamine, a teratogen produced by a

In the course of our continuing search for novel cancer chemopreventive agents from natural sources, several kinds of Labiatae plants were screened. Consequently, the iridoid glycoside derivative, 8-acetylharpagide (8-AcHarp), was obtained from the flowering whole plant of Ajuga decumbens as an

Sixteen compounds (1-16) isolated from the flowering whole plant of Ajuga decumbens have been tested for their inhibitory effects on Epstein-Barr virus early antigen (EBV-EA) induction by the tumor promoter, 12-O-tetradecanoylphorbol-13-acetate (TPA), as a primary screening test for

Objectives: Natural products originating from plants have been used for many years in the treatment of various diseases, including cancer. Centaurea solstitialis subsp. solstitialis is used in Turkish folk medicine. This study was the first to

In this study, in vitro inhibitory effects of 55 extracts or fractions obtained from 10 plant species on interleukin-1 (IL-1alpha, IL-1beta) and tumor necrosis factor (TNF-alpha) biosynthesis were studied. The following plant materials from Turkish folk medicine for the treatment of various diseases

The discovery of the JAK2V617F mutation triggered an unexpected flowering of basic and clinical studies in the field of myeloproliferative neoplasms (MPNs), resulting after just a few years in an exceptional amount of new information. One important consequence of those new findings was the

In the early 20th century, advocacy of the enzyme therapy of cancer was primarily the work of one man, John Beard, DSc (1858-1924). He and his collaborators made a determined effort to establish this mode of therapy, especially in the years 1905 to 1911. Despite a brief flowering of international

To explore in vitro anticancer potential of Aerva lanata L. (flowering aerial part). The study was performed with 5 different human cell lines for the study of lung, leukaemia, prostate, colon and cervix cancer by using Sulphorhodamine B (SRB) assay. There were three doses of 10, 30 and 100 microg

To obtain transformation of plant cells, we incubated 3-day-old cell wall-regenerating protoplasts from tobacco with Agrobacterium tumefaciens harboring tumor-inducing plasmids. Putative transformed tobacco cells were selected by phytohormone autotrophic growth and were shown to be transformed by
