Poisonous weeds are a global problem since they not only hinder local economic development, but also cause ecological harm. Consolida rugulosa (family Ranunculaceae) is a weed that is widespread in Northwestern China and causes severe poisoning when ingested by livestock. In the present study, we purified the toxins in this plant and investigated their mechanism of action. Five natural diterpene alkaloids (compounds 1-5)-including two new compounds (1 and 2)-were isolated, and five semi-synthetic derivatives (6-10) were synthesised based on 4 or 5 for structure-activity analysis. The toxicity of the compounds was evaluated in vitro with lactate dehydrogenase (LDH) assay. All of the compounds-especially 1-stimulated LDH release in primary cultured rat myocardial cells, an effect that was blocked by the Na+ channel blocker lidocaine. Electrocardiography revealed that rats treated with 1 had severe arrhythmia, while heart Doppler echocardiography and analysis of serum biomarkers levels revealed that administration of 1 for 15 days induced changes in cardiac structure and myocardial enzyme levels. These effects were antagonised by lidocaine treatment. Thus, diterpene alkaloids are the main compounds responsible for the cardiotoxicity of C. rugulosa, which can be mitigated by co-administration of lidocaine.

Prostate Cancer (PCa) is the most frequently diagnosed cancer in men in their late ’50s. PCa growth is mainly due to the activation of the androgen receptor by androgens. The treatment for PCa may involve surgery, hormonal therapy, and oral chemotherapeutic drugs. A structural based molecular docking approach revealed the findings of (E)-N’-((1-chloro-3,4-dihydronaphthalen-2-yl)methylene)benzohydrazide derivatives, where the possible binding modes of the compounds with protein (PDB ID: 3V49) are shown. The compounds (6a-k) were synthesized and characterized by using conventional methods. The compounds, 6g, 6j, and 6k were reconfirmed through single crystal X-ray diffraction (XRD). Further, the compounds (6a-k) and standard drug were evaluated against human prostate cancer cell lines, LNCaP and PC-3 and the non-cancerous cell line, 3T3. Among these compounds, 6g and 6j showed higher cytotoxicity, and 6g exhibited dose-dependent activity and reduced cell viability. The mechanism of action was observed through the induced apoptosis and was further confirmed by western blot and ELISA. Molecular dynamics simulation studies were carried out to calculate the interaction and the stability of the protein-ligand complex in motion. ADME properties were predicted for all the tested compounds. These findings may give vital information for further development.

Human DNA topoisomerase II is one of the major targets in anticancer therapy, however ATP-competitive inhibitors of this target have not yet reached their full potential. ATPase domain of human DNA topoisomerase II belongs to the GHKL ATPase superfamily and shares a very high 3D structural similarity with other superfamily members, including bacterial topoisomerases. In this work we report the discovery of a new chemotype of ATP-competitive inhibitors of human DNA topoisomerase II alpha that were discovered through screening of in-house library of ATP-competitive inhibitors of bacterial DNA gyrase and topoisomerase IV. Systematic screening of this library provided us with 20 hit compounds. 1,2,4-Substituted N-phenylpyrrolamides were selected for a further exploration which resulted in 13 new analogues, including 52 with potent activity in relaxation assay (IC50 = 3.2 mu M) and ATPase assay (IC50 = 0.43 mu M). Cytotoxic activity of all hits was determined in MCF-7 cancer cell line and the most potent compounds, 16 and 20, showed an IC50 value of 8.7 and 8.2 mu M, respectively.

In this study, a mild and efficient method is developed for the silylation of diverse functional groups using CeO2 nanoparticles (n-CeO2) as solid catalysts with hexamethyldisilazane (HMDS) as silylating agent at room temperature. Alcohols, phenols and acids are silylated to their respective silyl derivatives with faster reaction rate while amines and thiols required relatively longer reaction time. Moreover, the solid catalyst is easily be separated from the reaction mixture and recycled more than five times without any obvious decay in its activity. Powder X-ray diffraction (XRD), transmission electron microscope (TEM), UV-vis diffuse reflectance spectra (UV-DRS) and Raman analyses revealed identical structural integrity, particle size, absorption edge and valence state for the reused solid compared to the fresh solid catalyst.

Chiral total syntheses of all six insecticidal natural pyrethrins (three pyrethrin I and three pyrethrin II compounds) contained in the chrysanthemum (pyrethrum) flower were performed. Three common alcohol components [(S)-cinerolone, (S)-jasmololone, and (S)-pyrethrolone] were synthesized: (i) straightforward Sonogashira-type cross-couplings using available (S)-4-hydroxy-3-methyl-2-(2-propynyl)cyclopent-2-en-1-ones (the prallethrin alcohol) for (S)-cinerolone (overall 52% yield, 98% ee) and (S)-pyrethrolone (overall 54% yield, 98% ee) and (ii) traditional decarboxylative-aldol condensation and lipase-catalyzed optical resolution for (S)-jasmololone (overall 16% yield, 96% ee). Two counter acid segments [(1R,3R)-chrysanthemic acid (A) and (1R,3R)-second chrysanthemic acid precursor (B)] were prepared: (i) C(1) epimerization of ethyl (+/-)-chrysanthemates and optical resolution using (S)-naphthylethylamine to afford A (96% ee) and (ii) concise derivatization of A to B (96% ee). All six pyrethrin esters (cinerin I/II, jasmolin I/II, and pyrethrin I/II) were successfully synthesized utilizing an accessible esterification reagent (TsCl/N-methylimidazole). To investigate the stereostructure-activity relationship, all four chiral stereoisomers of cinerin I were synthesized. Three alternative syntheses of (+/-)-jasmololone were investigated (methods utilizing Piancatelli rearrangement, furan transformation, and 1-nitropropene transformation). Insecticidal activity assay (KD50 and IC50) against the common mosquito (Culex pipiens pallens) revealed that (i) pyrethrin I > pyrethrin II, (ii) pyrethrin I (II) >> cinerin I (II) >> jasmolin I (II), and (iii) natural cinerin I >> three unnatural cinerin I compounds (apparent chiral discrimination).

The hydroformylation of alkynes is a fundamental and important reaction in both academic research and industry. Conventional methods focus on the conversion of alkynes, CO, and H-2 into alpha,beta -unsaturated aldehydes, but they often suffer from problems associated with operation, regioselectivity, and chemoselectivity. Herein, we disclose an operationally simple, mild, and syngas-free rhodium-catalyzed reaction for the hydroformylation of alkynes via formyl and hydride transfer from an alkyl aldehyde. This synthetic method uses inexpensive and easy-to-handle n-butyraldehyde to overcome the challenge posed by the use of syngas in traditional approaches and employs a commercially available catalyst and ligand to transform a broad range of internal alkynes, especially alkynyl-containing complex molecules, into versatile stereodefined alpha,beta -unsaturated aldehydes with excellent chemo-, regio-, and stereoselectivity.

The effect of topology on the structure, self-assembly, and selective Fe3+ binding of delta-peptides has been investigated. A series of delta-peptides with an amino acid containing dihydropyrimidinone and o-, m-, and p-aminobenzoic acids have been designed to study the structure-function relationship. A new amino acid containing dihydropyrimidinone was synthesized by the Biginelli reaction of ethyl acetoacetate, urea, and o-nitrobenzaldehyde followed by reduction with iron powder and acetic acid. X-ray crystallography sheds some light on the conformations, self-assembly, and the diverse degrees of pi-pi stacking of adjacent delta-peptide molecules. Peptides with o- or m-aminobenzoic acid form eight-membered intramolecular hydrogen-bonded turn conformations and self-assemble through intermolecular hydrogen bonds between dihydropyrimidinone units to form a butterfly-like structure. However, the delta-peptide containing p-aminobenzoic acid forms a water-mediated cage-like structure. Irrespective of the presence of the same functional groups, only the delta-peptide with o-aminobenzoic acid can selectively bind Fe3+ in methanol as well as in water. The topology plays a crucial role in the selective Fe3+ ion binding by the delta-peptide.
