Paragraph: The binding between peptide epitopes and major histocompatibility complex proteins (MHCs) is an important event in the cellular immune response. Accurate prediction of the binding between short peptides and the MHC molecules has long been a principal challenge for immunoinformatics. Recently, the modeling of MHC-peptide binding has come to emphasize quantitative predictions: instead of categorizing peptides as "binders" or "non-binders" or as "strong binders" and "weak binders", recent methods seek to make predictions about precise binding affinities. We developed a quantitative support vector machine regression (SVR) approach, called SVRMHC, to model peptide-MHC binding affinities. As a non-linear method, SVRMHC was able to generate models that out-performed existing linear models, such as the "additive method". By adopting a new "11-factor encoding" scheme, SVRMHC takes into account similarities in the physicochemical properties of the amino acids constituting the input peptides. When applied to MHC-peptide binding data for three mouse class I MHC alleles, the SVRMHC models produced more accurate predictions than those produced previously. Furthermore, comparisons based on Receiver Operating Characteristic (ROC) analysis indicated that SVRMHC was able to outperform several prominent methods in identifying strongly binding peptides. As a method with demonstrated performance in the quantitative modeling of MHCpeptide binding and in identifying strong binders, SVRMHC is a promising immunoinformatics tool with not inconsiderable future potential.

Paragraph: A novel series of (3-diethoxyphosphoryl)isoxazolidines substituted at C5 with various quinazolinones have been synthesized by the 1,3-dipolar cycloaddition of N-methyl-C-(diethoxyphosphoryl)nitrone with N3-substitued 2-vinyl-3H-quinazolin-4-ones. All isoxazolidines were assessed for antiviral activity against a broad range of DNA and RNA viruses. Isoxazolidines trans-11f/cis-11f (90:10), trans-11h and trans-11i/cis-11i (97:3) showed weak activity (EC 50 = 6.84, 15.29 and 9.44 µM) toward VZV (TK + strain) which was only one order of magnitude lower than that of acyclovir used as a reference drug. Phosphonates trans-11b/cis-11b (90:10), trans-11c, trans-11e/cis-11e (90:10) and trans-11g appeared slightly active toward cytomegalovirus (EC 50 = 27-45 µM). Compounds containing benzyl substituents at N3 in the quinazolinone skeleton exhibited slight antiproliferative activity towards the tested immortalized cells with IC 50 in the 21-102 µM range.

Paragraph: Ubiquitin-like protease 1 (Ulp1) of Saccharomyces cerevisiae emerges as a fundamental tool to obtain the natural N-terminal target protein by cleavage of the small ubiquitin-related modifier (SUMO) fusion protein. However, the costly commercial Ulp1 and its complicated procedures limit its application in the preparation of the target protein with natural N-terminal sequence. Here, we describe the preparation of bioactive codon-optimized recombinant truncated Ulp1 (Leu403-Lys621) (rtUlp1) of S. cerevisiae in Escherichia coli using only one-step with Ni-NTA affinity chromatograph, and the application of rtUlp1 to cleave the SUMO fusion protein by simply mixing the purified rtUlp1, SUMO fusion protein and DL-Dithiothreitol in Tris-HCl buffer. The optimal expression level of nonfusion protein rtUlp1 accounts for approximately 50 % of the total cellular protein and 36 % of the soluble form by addition of isopropyl b-D-l-thiogalactopyranoside at a final concentration of 0.4 mM at 18°C for 20 h. The purification of target protein rtUlp1 was conducted by Ni-NTA affinity chromatography. The final yield of rtUlp1 was 45 mg/l in flask fermentation with a purity up to 95 %. Furthermore, the high purity of rtUlp1 could effectively cleave the SUMO-tTbRII fusion protein (SUMO gene fused to truncated transforming growth factor-beta receptor type II gene) with the above simplified approach, and the specific activity of the rtUlp1 reached up to 2.8 9 10 4 U/mg, which is comparable to the commercial Ulp1. The preparation and application strategy of the rtUlp1 with commonly available laboratory resources in this study will be convenient to the cleavage of the SUMO fusion protein to obtain the natural N-terminal target protein, which can be implemented in difficult-to-express protein functional analysis.
