Fumaria densiflora DC. Alkaloids

Twenty isoquinoline alkaloids were identified in the aerial part of Fumaria densiflora DC. In addition to bicuculline, densiflorine, fumaritine, fumariline, scoulerine, coptisine, cryptopine, parfumine, protopine, and sinactine which have been found previously, the following alkaloids were isolated for the first time from this species: adlumine, fumaricine, fumaritridine, fumarophycine, fumarofine, corytuberine, cis-N-methylstylopinium iodide, stylopine, and two new 1-benzylisoquinoline alkaloids, viz. fumaflorine and fumaflorine methyl ester. The cytoprotectivity of extracts of F. densiflora and F. officinalis, and that of protopine, cryptopine, and parfumine was tested on primary cultures of rat hepatocytes intoxicated with carbon tetrachloride. The cytoprotective effect of the extracts is associated with the alkaloids.

Identification of an anti-inflammatory derivative with anti-cancer potential: The impact of each of its structural components on inflammatory responses in macrophages and bladder cancer cells

Inflammation plays a crucial role in many types of cancer and is known to be involved in their initiation and promotion. As such, it is presently recognized as an important risk factor for several types of cancers such as bladder, prostate and breast cancers. The discovery of novel anti-inflammatory compounds can have a huge implication not only for the treatment of cancer but also as preventive and protective treatment modalities. We have recently identified a new compound (1) that presents interesting anti-inflammatory activity. In order to better understand its biological action, we have divided the molecule in its basic components and verified their respective contribution towards the anti-inflammatory response of the whole molecule. We have discovered that only the combination of the maleimide function together with the tert-butyloxycarbonylhydrazinamide function lead to important anti-inflammatory properties. The main derivative 1 can decrease the activating effects of INFgamma or IL6 on human (hMomegas) macrophages by 38% or by 64% at a concentration of 10 muM as indicated by a decrease of STAT1 or STAT3 activation. The expression of pro-inflammatory markers CD40 and MHCII in INFgamma stimulated hMomegas were reduced by 87% and 49%, respectively with a 3 h pretreatment of 1 at 10 muM. The cell motility assay revealed that 1 at 10 muM can reduce relative cell motility induced by IL6 by 92% in comparison with the untreated control hMomega monolayers. Compound 1 reduced by 91% the inflammatory response induced by the cytokines (INFgamma + TNFalpha) in the macrophage-like J774A.1 cells at a concentration of 25 muM, as measured by the detection of NO production with the Griess reagent. Furthermore, upon removal of the tert-butyloxycarbonyl protective group the unprotected derivative as a hydrochloride salt (1A) retains interesting anti-inflammatory activity and was found to be less toxic than the parent compound (1).

Practical synthesis of maleimides and coumarin-linked probes for protein and antibody labelling via reduction of native disulfides

The cellular tracking, detection and sensing of protein or antibody movement are important aspects to advance our understanding of biomolecular interactions and activity. Antibodies modified with fluorescent dyes are also valuable tools, especially in immunology research. We describe here a proof-of-principle study of a new water-soluble coumarin probe with a maleimide thiol-reacting unit to fluorescently tag biomolecules. Highlights include: (1) a convenient water-based preparation of N-substituted maleimides, (2) a one-pot preparation of activated maleimido-esters, and (3) a bio-conjugation protocol for the selenol-promoted reduction of native disulfide bonds and the ‘site-specific’ labelling of antibodies with no significant loss of activity.

Quantitative measurement of some physico-chemical parameters for the medicinally useful natural products

Lipinski’s rule of five is well received throughout the world and widely used as one of the basic filters to screen ligands for their druggability. In this direction, we have studied 148 biologically active natural products which are available as drugs. Physicochemical parameters such as molecular weight, logP, hydrogen bond donors, hydrogen bond acceptors, number of aromatic rings, molar refractivity and Gibbs free energy were calculated. Statistical results reveal that, they do fall under the Lipinski’s rule of 5 (RO5). The illustration about need for the study, methods followed and results obtained are reported here.

Discovery of an Orally Available Janus Kinase 3 Selective Covalent Inhibitor

JAK family kinases are important mediators of immune cell signaling and Janus Kinase 3 (JAK3) has long been indicated as a potential target for autoimmune disorders. Intensive efforts to develop highly selective JAK3 inhibitors have been underway for many years. However, because of JAK3’s strong binding preference to adenosine 5?-triphosphate (ATP), a number of inhibitors exhibit large gaps between enzymatic and cellular potency, which hampers efforts to dissect the roles of JAK3 in cellular settings. Using a targeted covalent inhibitor approach, we discovered compound 32, which overcame ATP competition (1 mM) in the enzymatic assay, and demonstrated significantly improved inhibitory activity for JAK3-dependent signaling in mouse CTLL-2 and human peripheral blood mononuclear cells. Compound 32 also exhibited high selectivity within the JAK family and good pharmacokinetic properties. Thus, it may serve as a highly valuable tool molecule to study the overlapping roles of JAK family kinases in complex biological settings. Our study also suggested that for covalent kinase inhibitors, especially those targeting kinases with low Km ATP values, the reversible interactions between molecules and proteins should be carefully optimized to improve the overall potency.

A new protoberberine alkaloid from Meconopsis simplicifolia (D. Don) Walpers with potent antimalarial activity against a multidrug resistant Plasmodium falciparum strain

Ethnopharmacological relevance The aerial components of Meconopsis simplicifolia (D. Don) Walpers are indicated in Bhutanese traditional medicine for treating malaria, coughs and colds, and the infections of the liver, lung and blood. This study is to validate the ethnopharmacological uses of this plant and also identify potent antimalarial drug leads through bioassays of its crude extracts and phytochemical constituents. Materials and methods Meconopsis simplicifolia (D. Don) Walpers was collected from Bhutan and its crude MeOH extract was subjected to acid-base fractionation. Through repeated extractions, separations and spectroscopic analysis, the alkaloids obtained were identified and tested for their antimalarial and cytotoxicity activities. Results Phytochemical studies resulted in the isolation of one new protoberberine type alkaloid which we named as simplicifolianine and five known alkaloids: protopine, norsanguinarine, dihydrosanguinarine, 6-methoxydihydrosanguinarine and oxysanguinarine. Among the five of the alkaloids tested, simplicifolianine showed the most potent antiplasmodial activities against the Plasmodium falciparum strains, TM4/8.2 (chloroquine-antifolate sensitive strain) and K1CB1 (multidrug resistant strain) with IC50 values of 0.78 mug/mL and 1.29 mug/mL, respectively. The compounds tested did not show any significant cytotoxicity activities against human oral carcinoma KB cells and normal Vero cells of African kidney epithelial cells. Conclusions This study validated the traditional uses of the plant for the treatment of malaria and identified a new alkaloid, simplicifolianine as a potential antimalarial drug lead.
