Studies on the application of Myceliophthora thermophila JCP1-4 cellulases cocktail on sugarcane bagasse pretreated by different methods

The hydrolysis step for sugar production in biorefineries is crucial for the sequential processes involved and cellulases cocktails behave differently according to the pretreatment employed. In this study, the application of the cellulases cocktail produced by the fungus Myceliophthora thermophila JCP1-4 was studied on the saccharification of sugarcane bagasse pretreated by ozonolysis and thermic ferric nitrate (TFN), and the results were compared with commercial enzymes (Novozymes Celluclast 1.5L, Novozym 188). The fungal cellulases cocktail hold an activity of FPU:β-glucosidase of 1:4(U/mL); time, temperature, FPU by g of cellulose load and percentage of dry matter (DM) were studied. The analysis of central composite design of TFN pretreated showed that fungal cellulases works better in DM values of 3–3.5% (4.5% for commercial), temperatures higher than 50 °C (<45 °C for commercial) and 15FPU for both; commercial enzymes yielded 7.78 g/L of reducing sugars and the fungal enzymes 5.42 g/L. With the ozone pretreated, the fungal enzymes presented a higher thermostability with faster kinects, being able to produce 5.56 g/L of reducing sugars (60 °C, 8 h), against 5.20 g/L for commercial enzymes (50 °C, 24 h), (10FPU, 3%DM for both). The FPU derivate analysis revels better yields with 7.5FPU, and the increase of DM to 7.5% resulted 13.28 g/L of reducing sugars.

A multicenter, multinational analysis of mitomycin C in refractory metastatic colorectal cancer

Background: A considerable number of metastatic colorectal cancer (mCRC) patients who progress on standard treatment with 5-fluorouracil (5FU), oxaliplatin, irinotecan and monoclonal antibodies, still have adequate performance status and desire further treatment. Mitomycin C (MMC) has been widely used in this context, and despite good tolerability, there are doubts regarding its true benefit. Methods: In order to assess the activity of MMC in the refractory mCRC setting, we retrospectively evaluated 109 heavily pre-treated patients who received MMC as single agent or in combination for mCRC at three different institutions in two countries. Results: Median patient's age was 54 years old, 57% were male and 94% had performance status ECOG 0 or 1. MMC was used in second line in 11%, third line in 38% and fourth line or beyond in 51% of patients. 58% received MMC combinations, mainly with capecitabine. Grade 3 or 4 toxicity was observed in 5% of patients and 6% required dose reductions. Median time to treatment failure (TTF) was 1.7 months with MMC and 3.6 months on the regimen prior to MMC, with a ratio between these TTF below 1 in 82% of patients. Median survival was only 4.5 months (95% confidence interval (CI) of 3.48-5.56). Conclusions: This retrospective data represent the largest reported series of unselected refractory mCRC patients treated with MMC. The median survival of 4.5 months is similar to the survival expected for best supportive care. This lack of activity strongly suggests that MMC should not be routinely used in refractory mCRC.

One-Pot, Three-Step Reaction of 5-[(Trimethylsilyl)ethynyl]pyrrolidin-2-one with Azides Catalyzed by Cu-I: Synthesis of a Novel Class of 1,4-Disubstituted 1,2,3-Triazoles

A very fast, easy and efficient synthesis is described for a novel and biologically important class of 1,4-disubstituted-4-(5-pyrrolidin-2-one)-1,2,3-triazoles by an ultrasound-assisted one-pot, three-step click reaction sequence of 5-[(trimethylsilyl)ethynyl]pyrrolidin-2-one with organic azides mediated by catalytic Cu-I salts.
