Cooperative catalysis by bovine serum albumin-iodine towards cascade oxidative coupling-C(sp2)-H sulfenylation of indoles/hydroxyaryls with thiophenols on water

Cooperative cascade catalysis by bovine serum albumin (BSA)-iodine allows for the first time the performance of C(sp2)-H sulfenylation of indole from readily available thiophenol (-SH bond) via in situ generation/cleavage of disulfide (S-S bond) in air under aqueous conditions, whereas BSA or I2 individually do not permit this two step sequence to occur in the same pot towards C-S bond formation. This green cooperative protocol is extendable to sulfenylation of hydroxyaryls (i.e. 2-naphthol or 4-hydroxycoumarin) with diverse thiols (aryl/heteroaryl) without using any toxic metal catalysts, bases or oxidants, thus rendering the process environmentally and economically reliable. Further, the gram scale synthesis of a COX-2 inhibitor (3-(pyridin-2-ylthio)-1H-indole), regioselectivity and recyclability (up to four cycles) are the additional merits of this cooperative cascade bio-chemocatalytic (BSA-I2) protocol. Moreover, HPLC and ESI-MS provide powerful insights into the mechanistic aspects of the above cascade sulfenylation reaction.

Ligand-enabled Ir-catalyzed intermolecular diastereoselective and enantioselective allylic alkylation of 3-substituted indoles

An Ir-catalyzed asymmetric allylic alkylation of 3-substituted indoles is reported. The reaction provides indoline products containing multiple contiguous stereocenters with high site-, regio-, diastereo- and enantioselectivities in one step from a wide range of readily available starting materials. The key to this method is the high level of diastereocontrol enabled by an iridium catalyst derived from a N-aryl phosphoramidite ligand (Me-THQphos, 1c).

Detection of melanochromes by MALDI-TOF mass spectrometry

Melanin formation from dopamine, DOPA, DHI, or DHICA, was analyzed by means of matrix-assisted laser desorption mass spectrometry. Oligomers of dihydroxyindoles, i.e. melanochromes, up to DP11 were detected. Increments of 16 mass units provide evidence for the presence of trihydroxyindole units. The results indicate that polymerization of dihydroxyindoles towards melanins occurs by sequential coupling of monomers with concomitant oxygenation.

Synthesis and characterisation of polymerisable photochromic spiropyrans: towards photomechanical biomaterials

A methodology for the synthesis of novel polymerisable spiropyrans with photomechanical properties suitable for subsequent copolymerisation with either vinyl or acrylate-based biomaterials is described. UV-vis spectroscopic characterisation of photoisomerism shows that photochromic behaviour with respect to related non-polymerisable compounds is retained and is solvent dependent. In acetone, conventional spiropyran-merocyanine photochromism is observed for nitro-spiropyran derivatives, whereas in dichloromethane both nitro-spiropyrans and spiropyrans isomerise to merocyanines which rapidly form H-aggregates. The monomers were designed such that an alkyl spacer of variable length, both electronically and sterically, separates the polymerisable moiety from the photochromic core and allows steric aspects of the resulting photomechanical behaviour to be explored.

Discovery of VX-509 (Decernotinib): A Potent and Selective Janus Kinase 3 Inhibitor for the Treatment of Autoimmune Diseases

While several therapeutic options exist, the need for more effective, safe, and convenient treatment for a variety of autoimmune diseases persists. Targeting the Janus tyrosine kinases (JAKs), which play essential roles in cell signaling responses and can contribute to aberrant immune function associated with disease, has emerged as a novel and attractive approach for the development of new autoimmune disease therapies. We screened our compound library against JAK3, a key signaling kinase in immune cells, and identified multiple scaffolds showing good inhibitory activity for this kinase. A particular scaffold of interest, the 1H-pyrrolo[2,3-b]pyridine series (7-azaindoles), was selected for further optimization in part on the basis of binding affinity (Ki) as well as on the basis of cellular potency. Optimization of this chemical series led to the identification of VX-509 (decernotinib), a novel, potent, and selective JAK3 inhibitor, which demonstrates good efficacy in vivo in the rat host versus graft model (HvG). On the basis of these findings, it appears that VX-509 offers potential for the treatment of a variety of autoimmune diseases.

3D tailored design as a bioremediation strategy for a lagoon in Matanza-Riachuelo basin

A native strain of the microalgae Chlorella vugaris was shown to be effective for the reduction of several chemical and microbial contaminants present in polluted streams from the Matanza-Riachuelo Basin (M-R, 1). The microalgae immobilization in calcium alginate beads protects the cells from the toxic effects of numerous substances and from extreme pH and temperatures, allowing better survival and greater efficiency in the production of biomass [2, 3]. However, cells trapped in the matrix are easy to be devoured by the fauna existent. Saladita Norte lagoon is part of M-R, this watercourse exhibits a wide range of contaminants levels along the year, mainly depending on the seasonal regime. At certain periods of the year, these levels usually exceed the limits established in international standards of water quality [4-6]. Similarly to that observed in other streams of M-R, several nitrogenated compounds, phosphorus, metals, and saprophytic and pathogenic bacteria are the main contaminants of Saladita Norte. In order to protect the alginate beads from the birds and fishes predation, a 3D-printed PLA (polylactic acid) device was designed. PLA is a biocompatible and biodegradable material that has been described as suitable for biotechnological applications. [7]. Bioprocesses carried out with this material must be checked for mechanical stability and optimal pore size to allow an effective bioremediation process. For this purpose, we used a stirredtank bioreactor supplied with a marine propeller and aeration during 6 days. Growth index and biomass production were compared between algae immobilized in alginate beads versus immobilized in alginate beads placed into a complex 3D printed PLA device. As previously observed, our native isolate of C. vulgaris could grow inside the alginate beads based on the consumption of several of the above-mentioned contaminants, such as phosphorus and nitrogenated ions [1]. The results obtained in control treatments with immobilized cells in alginate beads were: A- MS synthetic culture media supplemented with sucrose (3% w/v) and indolacetic acid (1 mg/L) as growth regulator [1] (mu=0.737, dt= 24 h) and B- as A- but growing in Saladita Norte water (mu=0.668, dt= 24 h). Also, treatments using 3D-device were: C- like B, but Chlorella cultures immobilized in alginate beads growing into a PLA3D scaffold coloured red (mu=0.341, dt= 2 d); D- like C, but coloured white (mu=0.206, dt= 3 d); and E- like C, but uncoloured (mu=0.342, dt= 2 d) were effective and successful to bioremediation in vitro. All cultures were kept at 24¡À2C, with a photoperiod of 16 h under PAR (above 400 mumol photon m-2 s-1). The data obtained were complemented with standardized cytotoxicity tests using Allium cepa and Lactuca sativa seeds. Germination rate and mitotic index of onion seeds and germination rate and length of lettuce seeds using polluted water or bioremediated water were compared. The results obtained demonstrate the potential of this technology to be used in integrated processes that seek removal of xenobiotics.
