Abstract
An eco-friendly approach for electrochemical radical cascade annulation of 1,2,3-benzotriazinones with alkynes is described. Under catalyst-free and external reductant-free electrolysis conditions, a range of isoquinolin-1(2H)-ones were obtained in moderate to good yields. Cyclic voltammetry and control studies suggest that the reaction proceeds via a radical pathway. Furthermore, this approach could be easily scaled up.

Abstract
A Cu-catalyzed oxidative dual arylation of active alkenes via the cleavage of two C-N bonds of 3-aminoindazoles is presented for constructing isoquinolinones. Importantly, 3-aminoindazoles are used as efficient arylating agents through a radical process. This method has a good substrate scope and functional group compatibility.

Abstract
Asymmetric palladium-catalyzed arylboration/cyclization of both nonactivated and activated alkenes with B2pin2 was developed. A wide range of N-allyl-o-iodobenzamides and o-iodoacryanilides reacted with B2pin2 to afford borylated 3,4-dihydroisoquinolinones and oxindoles, respectively, in high yields with high enantioselectivities. The synthetic utility of this enantioselective protocol was highlighted by synthesizing various chiral 3,4-dihydroisoquinolinone and oxindole derivatives containing quaternary stereogenic carbon centers, including enantioenriched Roche anticancer agent (S)-RO4999200.

Abstract
In this study, we used ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) to measure the concentration of narciclasine and 7-deoxynarciclasine in mouse blood after intravenous (i.v.) and oral administration (p.o.), and we used this method to investigate their pharmacokinetics profiles in mice. Chromatographic separation of the analytes was achieved using a UPLC HSS T3 column (2.1 mm × 100 mm, 1.8 μm) with a mobile phase consisting of acetonitrile-water (0.1% formic acid) by gradient elution. Electrospray ionization (ESI positive-ion mode)-tandem mass spectrometry in multiple reaction monitoring (MRM) mode was employed for quantitative analysis of the analytes in mouse blood samples. Twelve mice were administered narciclasine and 7-deoxynarciclasine (2 mg/kg) intravenously (iv), while the other twelve mice were administered narciclasine and 7-deoxynarciclasine (10 mg/kg) orally. The mouse blood was withdrawn from the caudal vein to be processed, after which the blood was analyzed by UPLC-MS/MS, and the corresponding data were fitted using the Drug and Statistics (DAS) software. Standard curves of narciclasine and 7-deoxynarciclasine were generated over the concentration range of 5-5000 ng/mL. The intra-day accuracy of narciclasine and 7-deoxynarciclasine was 90-105%, and the corresponding inter-day accuracy was 87-108%. The intra-day precision was less than 13%, while the inter-day precision was less than 14%. Matrix effects were also observed (between 94% and 104%), and the recovery calculated was higher than 70%. The developed and validated UPLC-MS/MS method was then successfully applied in determining the mouse pharmacokinetics of narciclasine and 7-deoxynarciclasine. From this, thebioavailabilityofnarciclasine and 7-deoxynarciclasinewasdetermined to be 10.3%and35.4%, respectively.

Abstract
![]()
Highly substituted isoquinolone-4-carboxylic
acid is an important
bioactive scaffold; however, it is challenging to access it in a general
and short way. A Cu-catalyzed cascade reaction was successfully designed
involving the Ugi postcyclization strategy by using ammonia and 2-halobenzoic
acids as crucial building blocks. Privileged polysubstituted isoquinolin-1(2H)-ones were constructed in a combinatorial format with
generally moderate to good yields. The protocol, with a ligand-free
catalytic system, shows a broad substrate scope and good functional
group tolerance toward excellent molecular diversity. Free 4-carboxy-isoquinolone
is now for the first time generally accessible by a convergent multicomponent
reaction protocol.

Abstract
Minalrestat and its analogues represent structurally novel aldose reductase inhibitors, and the asymmetric synthesis of such pharmaceutically privileged molecules has not been reported yet. We have developed a palladium-catalyzed enantioselective intramolecular carbonylative Heck reaction by using formate esters as the source of CO, which represents the first enantioselective synthesis of quaternary 3,4-dihydroisoquinolines. The reaction provides a facile and efficient method for the synthesis of enantiopure nitrogen-containing heterocyclic compounds bearing an all-carbon quaternary stereocenter. The reaction has been successfully applied to the first asymmetric synthesis of Minalrestat analogues.

Abstract
An efficient Ru(ii)-catalyzed site-selective C-H arylation of 2-pyridones and 1-isoquinolinones was achieved with boronic acids by using pyridine as a directing group. The developed protocol is general and provides rapid access to an array of C6-arylated 2-pyridones and C3-arylated 1-isoquinolinones in excellent yields. These designed arylated 2-pyridones and 1-isoquinolinones can serve as key structural motifs for accessing functionalized pyridines and isoquinolines.

Abstract
A feasible and enantioselective total synthesis of (-)-trans-dihydronarciclasine [(-)-1], a highly biologically active alkaloid, was devised starting from vanillin (8). The key step of this new synthesis was an asymmetric, organocatalytic Michael addition, in which an optically active nitropentanone [(-)-13] was obtained from a butenone derivative (12). Excellent enantioselectivity (>99% ee) was achieved using the (8S,9S)-9-amino(9-deoxy)epiquinine (16) organocatalyst. The target molecule can be prepared in 13 steps from compound (-)-13. The total synthesis has provided a facile and first access to the ent-form of naturally occurring (+)-trans-dihydronarciclasine, a highly potent cytostatic alkaloid.

Abstract
The catalyst-controlled C4/C8 site-selective C-H arylation of isoquinolones using aryliodonium salts as the coupling partners was developed. The C4-selective arylation was successfully achieved via an electrophilic palladation pathway. A completely different selectivity pattern was observed using an Ir(III) catalytic system, which resulted in C-C bond formation exclusively at the C8 position. The isoquinolone scaffold can be conveniently equipped with various aryl substituents at either the C4 or C8 position.

Abstract
Lophocereus schottii is a Mexican cactus known as garambullo whose bark is used for the treatment of cancer, diabetes, ulcers, sores, stomach disorders and tuberculosis. The aim of this study was to evaluate the cytotoxic effect of the ethanolic extract of bark of L. Schottii. To assess these effects we established a flow of experiments in a model of BALB/c mice murine lymphoma. We value first survival of mice inoculated with 2 × 10(4) L5178Y murine lymphoma cells, orally treated with 10 mg/Kg of the extract for 10 consecutive days; the second assessment was to determine the influence of the immune system, we carry out studies of lymphoproliferation in mice with the same conditions of the previous study, only that the treatment was for 22 days before the completion cell cultures; the third study was to establish the cytotoxic effect of extract of L. schottii using different concentrations, by murine lymphoma cell cultures and splenocytes from healthy mice and finally we assessed the effect in vivo of extract of L. Schottii in a model of solid murine lymphoma inoculating 1 × 10(7) lymphoma cells in the gastrocnemius muscle observing the development of the tumor. We observed that oral treatment of 10 mg/kg of extract of L. schottii increased survival rate in treated mice; additionally, an intratumoral injection of 50 and 100 mg/kg in a solid murine lymphoma located in the gastrocnemius muscle, allowed a significantly slower tumor evolution. In vitro studies determined that extract inhibited 63% of lymphoma cell growth. With these evidences it is feasible to scientifically validate that ethanolic extract of L. schottii had an effect on L5178Y murine cells lymphoma and could have the same effect in human tumors.

Abstract
The anti hepatitis C virus (HCV) activity of (+)-lycoricidine (1) was evaluated for the first time in this letter, yielding an EC50 value of 0.55 nmol/mL and an selection index (SI) value of 12.72. Further studies indicated that 1 induced this effect by down-regulating host heat-stress cognate 70 (Hsc70) expression. In addition, 20 derivatives were designed and synthesised to investigate the basic structure-activity relationship (SAR) of the title compound. Several of these derivatives exhibit a good inhibition of HCV, such as compound 3 (EC50=0.68 nmol/mL, SI=33.86), compound 2d (EC50=15 nmol/mL, SI=12) and compound 5 (EC50=33 nmol/mL, SI >10.91). Meanwhile, the experimental data suggest that the modification of certain groups of (+)-lycoricidine can reduce the cytotoxicity of the compounds.

Abstract
Several C-1 homologues of pancratistatin and 7-deoxypancratistatin were synthesized by a phenanthrene-phenathridone oxidative recyclization strategy. The key steps involved the enzymatic dihydroxylation of bromobenzene, addition of an aryl alane to an epoxyaziridine, an intramolecular aziridine opening on silica gel in solid phase, and the above-mentioned recylization strategy. Experimental and spectral data are reported for all new compounds. All synthesized C-1 homologues of pancratistatin and 7-deoxypancratistatin were evaluated for antiproliferative activity in a panel of human cancer cell lines. As expected, the 7-hydroxy compounds were found to be more potent and the activity of the C-1 benzoxymethyl analogue exceeded that of narciclasine, which was used as a positive control.

Abstract
The anticancer activity of Amaryllidaceae isocarbostyrils is well documented. At pharmacological concentrations, that is, approximately 1 μM in vitro and approximately 10 mg/kg in vivo, narciclasine displays marked proapoptotic and cytotoxic activity, as does pancratistatin, and significant in vivo anticancer effects in various experimental models, but it is also associated with severe toxic side effects. At physiological doses, that is, approximately 50 nM in vitro and approximately 1 mg/kg in vivo, narciclasine is not cytotoxic but cytostatic and displays marked anticancer activity in vivo in experimental models of brain cancer (including gliomas and brain metastases), but it is not associated with toxic side effects. The cytostatic activity of narciclasine involves the impairment of actin cytoskeleton organization by targeting GTPases, including RhoA and the elongation factor eEF1A. We have demonstrated that chronic treatments of narciclasine (1 mg/kg) significantly increased the survival of immunodeficient mice orthotopically xenografted with highly invasive human glioblastomas and apoptosis-resistant brain metastases, including melanoma- and non-small-cell-lung cancer- (NSCLC) related brain metastases. Thus, narciclasine is a potentially promising agent for the treatment of primary brain cancers and various brain metastases. To date, efforts to develop synthetic analogs with anticancer properties superior to those of narciclasine have failed; thus, research efforts are now focused on narciclasine prodrugs.

Abstract
The C21-C34 fragment of the potent FKBP12-binding macrolide antascomicin B was prepared using Ireland-Claisen and allylic diazene rearrangements to establish the C26/C27 and the C23 stereocenters, respectively. Directed hydrogenation installed the C29 β-configuration. The fragment possesses 7 of the 11 fixed stereocenters contained in the natural product.

Abstract
The naturally occurring Amaryllidaceae alkaloid pancratistatin exhibits potent apoptotic activity against a large panel of cancer cells lines and has an insignificant effect on noncancerous cell lines, although with an elusive cellular target. Many current chemotherapeutics induce apoptosis via genotoxic mechanisms and thus have low selectivity. The observed selectivity of pancratistatin for cancer cells promoted us to consider the hypothesis that this alkaloid targets cancer cell mitochondria rather than DNA or its replicative machinery. In this study, we report that pancratistatin decreased mitochondrial membrane potential and induced apoptotic nuclear morphology in p53-mutant (HT-29) and wild-type p53 (HCT116) colorectal carcinoma cell lines, but not in noncancerous colon fibroblast (CCD-18Co) cells. Interestingly, pancratistatin was found to be ineffective against mtDNA-depleted (ρ(0)) cancer cells. Moreover, pancratistatin induced cell death in a manner independent of Bax and caspase activation, and did not alter β-tubulin polymerization rate nor cause double-stranded DNA breaks. For the first time we report the efficacy of pancratistatin in vivo against human colorectal adenocarcinoma xenografts. Intratumor administration of pancratistatin (3 mg/kg) caused significant reduction in the growth of subcutaneous HT-29 tumors in Nu/Nu mice (n = 6), with no apparent toxicity to the liver or kidneys as indicated by histopathologic analysis and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling. Altogether, this work suggests that pancratistatin may be a novel mitochondria-targeting compound that selectively induces apoptosis in cancer cells and significantly reduces tumor growth.

Synthesis of C-1 homologues of pancratistatin and their preliminary biological evaluation. Bioorg Med Chem Lett 2011; 21:4750-2. [PMID: 21757350 DOI: 10.1016/j.bmcl.2011.06.068] [Citation(s) in RCA: 27] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2011] [Revised: 06/13/2011] [Accepted: 06/15/2011] [Indexed: 10/18/2022]
Abstract
The synthesis of two C-1 analogues of pancratistatin has been accomplished in 17 steps from bromobenzene. The key steps involved the enzymatic dihydroxylation, regioselective opening of epoxyaziridine 9 with the alane derived from 8, a solid-state silica-gel-catalyzed intramolecular opening of aziridine to produce phenanthrene 13 whose oxidative cleavage and recyclization provided the full skeleton of the Amaryllidaceae constituents. The new analogues 5 and 6 exhibited promising activity in several human cancer cell lines.

Abstract
The cytochrome P45O activities of the naturally occurring Amaryllidaceae alkaloid narciclasine (3), isolated from Narcissus pseudonarcissus, and synthetic derivative trans-dihydronarciclasine (5) are reported. While narciclasine was found to possess potent inhibitory activity to human CYP3A4, its dihydro analogue was inactive. This study revealed that the C1-C10b double bond is required for inhibition of this crucial metabolizing enzyme. Compound 5 also demonstrated no inhibition of the related human cytochromes CYP19 and CYP1A1. This study elevates the status of trans-dihydronarciclasine (5) as a highly privileged, readily available molecule, with potent and selective anticancer activity.

Abstract
Melanomas display poor response rates to adjuvant therapies because of their intrinsic resistance to proapoptotic stimuli. This study indicates that such resistance can be overcome, at least partly, through the targeting of eEF1A elongation factor with narciclasine, an Amaryllidaceae isocarbostyril controlling plant growth. Narciclasine displays IC(50) growth inhibitory values between 30-100 nM in melanoma cell lines, irrespective of their levels of resistance to proapoptotic stimuli. Normal noncancerous cell lines are much less affected. At nontoxic doses, narciclasine also significantly improves (P=0.004) the survival of mice bearing metastatic apoptosis-resistant melanoma xenografts in their brain. The eEF1A targeting with narciclasine (50 nM) leads to 1) marked actin cytoskeleton disorganization, resulting in cytokinesis impairment, and 2) protein synthesis impairment (elongation and initiation steps), whereas apoptosis is induced at higher doses only (≥200 nM). In addition to molecular docking validation and identification of potential binding sites, we biochemically confirmed that narciclasine directly binds to human recombinant and yeast-purified eEF1A in a nanomolar range, but not to actin or elongation factor 2, and that 5 nM narciclasine is sufficient to impair eEF1A-related actin bundling activity. eEF1A is thus a potential target to combat melanomas regardless of their apoptosis-sensitivity, and this finding reconciles the pleiotropic cytostatic of narciclasine. -

Abstract
An efficient synthesis of C-1 derivatives of 7-deoxypancratistatin is reported. The key steps include the following: selective opening of an epoxide with aluminum acetylide in the presence of an aziridine; solid-state silica-gel-catalyzed opening of an aziridine; and oxidative cleavage of a phenanthrene core and its recyclization to phenanthridone to provide the key C-1 aldehyde 22. The conversion of this aldehyde to C-1 acetoxymethyl and C-1 hydroxymethyl derivatives is described along with the evaluation of their biological activity against several cancer cell lines and in an apoptosis study. The C-1 acetoxymethyl derivative has shown promising activity comparable to that of the natural product. In addition, a total synthesis of trans-dihydrolycoricidine and a formal total synthesis of 7-deoxypancratistatin are reported from aldehyde 22. Detailed experimental and spectral data are provided for all new compounds.
