Catechol-modified poly(oxazoline)s with tunable degradability facilitate cell invasion and lateral cartilage integration

Tissue adhesives play an important role in clinical applications and may aid in the treatment of cartilage defects for improved cartilage integration. However, many fail to satisfy the demand for adequate adhesive strength on wet tissue surfaces and to facilitate sufficient cell migration and extracellular matrix (ECM) deposition at the defect site. Utilizing poly(2-alkyl-2-oxazoline) (POx)-based polymers equipped with mussel-inspired adhesion moieties and combining them with the natural wound sealant fibrinogen, we fabricated an adhesive biosynthethic hydrogel with tunable mechanical properties and improved bonding strength. Degradation of the hydrogels could be adjusted by the ratio of amide to ester linkages of the catecholic functional group at the POx side chain. In an in vitro disc/ring model for lateral cartilage integration, a benefit in long-term integration was observed with enhanced degradation of the adhesive without the expense of bonding strength. Incorporation of degradable ester linkages in the polymer facilitated cell invasion and strong deposition of cartilaginous ECM at the defect site. Overall, the results suggest that the presented injectable adhesive hydrogel, due to its easy tunability, holds great potential for cartilage defect treatment and other medical applications.

Total Synthesis of Lycoricidine and Narciclasine by Chemical Dearomatization of Bromobenzene

The total synthesis of lycoricidine and narciclasine is enabled by an arenophile-mediated dearomative dihydroxylation of bromobenzene. Subsequent transpositive Suzuki coupling and cycloreversion deliver a key biaryl dihydrodiol intermediate, which is rapidly converted into lycoricidine through site-selective syn-1,4-hydroxyamination and deprotection. The total synthesis of narciclasine is accomplished by the late-stage, amide-directed C-H hydroxylation of a lycoricidine intermediate. Moreover, the general applicability of this strategy to access dihydroxylated biphenyls is demonstrated with several examples.

Spectroscopic, X-ray Diffraction and Density Functional Theory Study of Intra- and Intermolecular Hydrogen Bonds in Ortho-(4-tolylsulfonamido)benzamides

The conformations of the title compounds were determined in solution (NMR and UV-Vis spectroscopy) and in the solid state (FT-IR and XRD), complemented with density functional theory (DFT) in the gas phase. The nonequivalence of the amide protons of these compounds due to the hindered rotation of the C(O)-NH2 single bond resulted in two distinct resonances of different chemical shift values in the aromatic region of their H-1-NMR spectra. Intramolecular hydrogen bonding interactions between the carbonyl oxygen and the sulfonamide hydrogen atom were observed in the solution phase and solid state. XRD confirmed the ability of the amide moiety of this class of compounds to function as a hydrogen bond acceptor to form a six-membered hydrogen bonded ring and a donor simultaneously to form intermolecular hydrogen bonded complexes of the type N-H center dot center dot center dot O=S. The distorted tetrahedral geometry of the sulfur atom resulted in a deviation of the sulfonamide moiety from co-planarity of the anthranilamide scaffold, and this geometry enabled oxygen atoms to form hydrogen bonds in higher dimensions.

A green and efficient method for the synthesis of pyrroles using a deep eutectic solvent ([CholineCl][ZnCl2](3)) under solvent-free sonication

An efficient deep eutectic solvent-based synthesis of pyrroles under ultrasound irradiation has been developed to provide a significant improvement of the yield up to 99% in a short reaction time. The synthesis of pyrroles is highly atom-economical, producing water as the sole byproduct. In addition, [CholineCl][ZnCl2](3) is easily synthesized from commercially available choline chloride and zinc chloride via a cost-effective and environmentally benign pathway. The obtained [CholineCl][ZnCl2](3) has been characterized by FT-IR, H-1-NMR, C-13-NMR, HRMS (ESI), Raman, and TGA. Five new pyrroles are synthesized by the current method. Moreover, [CholineCl][ZnCl2](3) could be reused up to four times without significant loss of catalytic activity.

Metabolomic approach of the antiprotozoal activity of medicinal Piper species used in Peruvian Amazon

Ethnopharmacological relevance: In the Peruvian Amazon as in the tropical countries of South America, the use of medicinal Piper species (cordoncillos) is common practice, particularly against symptoms of infection by protozoal parasites. However, there is few documented information about the practical aspects of their use and few scientific validation. The starting point of this work was a set of interviews of people living in six rural communities from the Peruvian Amazon (Alto Amazonas Province) about their uses of plants from Piper genus: one community of Amerindian native people (Shawi community) and five communities of mestizos. Infections caused by parasitic protozoa take a huge toll on public health in the Amazonian communities, who partly fight it using traditional remedies. Validation of these traditional practices contributes to public health care efficiency and may help to identify new antiprotozoal compounds. Aims of study: To record and validate the use of medicinal Piper species by rural people of Alto Amazonas Province (Peru) and annotate active compounds using a correlation study and a data mining approach. Materials and methods: Rural communities were interviewed about traditional medication against parasite infections with medicinal Piper species. Ethnopharmacological surveys were undertaken in five mestizo villages, namely: Nueva Arica, Shucushuyacu, Parinari, Lagunas and Esperanza, and one Shawi community (Balsapuerto village). All communities belong to the Alto Amazonas Province (Loreto region, Peru). Seventeen Piper species were collected according to their traditional use for the treatment of parasitic diseases, 35 extracts (leaves or leaves and stems) were tested in vitro on P. falciparum (3D7 chloroquine-sensitive strain and W2 chloroquineresistant strain), Leishmania donovani LV9 strain and Trypanosoma brucei gambiense. Assessments were performed on HUVEC cells and RAW 264.7 macrophages. The annotation of active compounds was realized by metabolomic analysis and molecular networking approach. Results: Nine extracts were active (IC50 <= 10 mu g/mL) on 3D7 P. falciparum and only one on W2 P. falciparum, six on L. donovani (axenic and intramacrophagic amastigotes) and seven on Trypanosoma brucei gambiense. Only one extract was active on all three parasites (P. lineatum). After metabolomic analyses and annotation of compounds active on Leishmania, P. strigosum and P. pseudoarboreum were considered as potential sources of leishmanicidal compounds. Conclusions: This ethnopharmacological study and the associated in vitro bioassays corroborated the relevance of use of Piper species in the Amazonian traditional medicine, especially in Peru. A series of Piper species with few previously available phytochemical data have good antiprotozoal activity and could be a starting point for subsequent promising work. Metabolomic approach appears to be a smart, quick but still limited methodology to identify compounds with high probability of biological activity.

Synthesis of Mepivacaine and Its Analogues by a Continuous-Flow Tandem Hydrogenation/Reductive Amination Strategy

Herein we report a convenient, fast, and high-yielding method for the generation of the racemic amide anaesthetics mepivacaine, ropivacaine, and bupivacaine. Coupling of -picolinic acid and 2,6-xylidine under sealed-vessel microwave conditions generates the intermediate amide after a reaction time of only 5 min at 150 degrees C. Subsequent reaction in a continuous-flow high-pressure hydrogenator (H-Cube Pro(TM)) in the presence of the respective aldehyde directly converts the intermediate to the final amide anaesthetics in a continuous, integrated, multi-step ring-hydrogenation/reductive amination protocol. Merits and limitations of the protocol are discussed.

Ugi multicomponent-reaction: Syntheses of cytotoxic dehydroabietylamine derivatives

Isocyanide-based multicomponent reactions – especially the standard four component Ugi reaction – provide an easy and powerful access to compounds with an auspicious pharmacological potential. Therefore, a set of 16 novel derivatives of the diterpene dehydroabietylamine was synthesized by the Ugi-4CR. The subsequent screening of the synthesized alpha-acylamino carboxamides in colorimetric sulforhodamine B assays revealed an in vitro cytotoxicity towards several human tumor cell lines. Particularly, the rhodamine B conjugates 14-16 showed a remarkable cytotoxic activity, characterized by EC50 values in a low three-digit nanomolar range. The screening of rhodamine B amide 17 that was obtained for comparison by a Schotten-Baumann reaction showed that the linkage of the rhodamine B moiety and the diterpene influences significantly its cytotoxic potency. While 14 was highly cytotoxic and acted as a mitocan, compound 17 was not cytotoxic a all. This observation underlines the importance of the type of coupling between the diterpene and the rhodamine part. The presence of a rhodamine B moiety in the molecules doesn’t necessarily guarantee that the compound is cytotoxic.

Aminopeptidase-N-activated Theranostic Prodrug for NIR Tracking of Local Tumor Chemotherapy

The development of molecular theranostic prodrugs for in vivo cancer diagnosis and targeted chemotherapy is urgently required. Enzyme-activated prodrugs display superior selectivity as a result of cancer-specific enzymes which serve as cancer biomarkers. Herein, an aminopeptidase N (APN)-activated theranostic prodrug Nile blue-C-6-amide-p-fluorophenylalanyl-l-melphalanyl (NBFMel) is reported for fluorescence cancer diagnosis and local tumor treatment. NBFMel demonstrates negligible cytotoxicity and very weak fluorescence due to the photoinduced electron transfer (PET) between melphalan and Nile blue fluorophore. After activation caused by APN, the prodrug releases free melphalan that inhibits tumor cell growth. Simultaneously, the reaction blocks the PET process and switches on the fluorescence, which can be used for cancer diagnosis. NBFMel is successfully utilized to report the presence of tumor and for in situ tracking of drug release in tumor-bearing mouse models. Moreover, NBFMel demonstrates efficient tumor inhibition when intravenously injected into mice. Therefore, the APN-activated theranostic prodrug provides a new platform for in vivo cancer diagnosis and targeted anticancer chemotherapy.

Crystallization behavior of poly(lactic acid) with a self-assembly aryl amide nucleating agent probed by real-time infrared spectroscopy and X-ray diffraction

The effect of a self-assembly nucleating agent, N,N’,N-tricyclohexy1-1,3,5-benzenetricarboxylamide (BTCA), on the crystallization behavior of poly(lactic acid) (PLA) was probed by time-resolved Fourier transform infrared spectroscopy (FTIR) and wide angle X-ray diffraction (WAXD). The vibrational changes associated with inter and intra-chain interactions during crystallization were monitored. In the initial period of crystallization, the order of intensity changes is as follows: 1458 cm(-1) > 1210 cm(-1) 921 cm(-1), 1458 cm(-1) similar to 1210 cm(-1) > 921 cm(-1), and 1458 cm(-1) similar to 1210 cm(-1) similar to 921 cm(-1) for neat PLA, PLAs containing 0.1 wt% and 0.3 wt% BTCA, respectively. This indicates that BTCA can accelerate both the formation of skeletal conformational-ordered structure and, especially, the 10(3) helix one. The incorporation of BTCA changes the crystallization mechanism but has no impact on the crystal form of PLA.
