标题:A Practical Strategy For The Synthesis Of 2-Dialkylamino-4-Arylamino-6-Aminopyrimidines
摘要:Starting From Commercially Available 4-Amino-2,6-Dichloropyrimidine,A Practical Four Steps Synthesis Of 2-Dialkylamino-4-Arylamino-6-Aminopyrimidines Was Developed. This Strategy Could Introduce A Diverse Set Of Secondary Amines And Arylamines To Displace The 2-And 4-Chloro Groups. The Products Of This Route Are Otherwise Difficult To Access. In Addition,6-Amino Arylation Was Carried Out To Demonstrate The Reactivity And Utility Of 2-Dialkylamino-4-Arylamino-6-Aminopyrimidines As Building Blocks For Assembling Interesting Aminopyrimidine Molecules.

摘要:The instant invention comprises a process for the solid phase synthesis of directed epitope peptide mixtures useful in the treatment and diagnosis of protein conformational disorders, such process defined by a set of rules regarding the identity and the frequency of occurrence of amino acids that substitute a base or native amino acid of a known epitope. The resulting composition is a mixture of related peptides for therapeutic use. The invention also pertains to the process of generating antibodies using the directed epitope peptide mixtures as the antigens, and antibodies generated by such process, useful in the treatment and diagnostics of the said protein conformational disorder.

摘要:Many Gram-negative pathogens assemble adhesive structures on their surfaces that allow them to colonize host tissues and cause disease. Novel compositions which inhibit or prevent the formation of a pilus chaperone-subunit complex are disclosed. Interfering with the function of the pili chaperone negatively affects the chaperone/usher pathway which is one molecular mechanism by which Gram-negative bacteria assemble adhesive pili structures and thus prevent or inhibit pilus assembly. Also provided are methods for the treatment or prevention of diseases caused by tissue-adhering pilus-forming bacteria by inhibiting the function of pilus chaperones. Also provided are pharmaceutical preparations capable of inhibiting or preventing the formation of a pilus chaperone-subunit complex. Also provided are methods of synthesizing the N-substituted amino acid compounds and compounds useful for the synthesis thereof. In particular, novel fluorinated linker compounds and methods of synthesis are provided. Methods for using the fluorinated linker compounds in methods of solid-phase synthesis of the N-substituted amino acid compounds are also disclosed.

标 题 :Primer-independent DNA polymerases and their use for DNA synthesis
发明人：SALAS FALGUERAS MARGARITA; REDREJO RODRIGUEZ MODESTO; KRUPOVIC MART; FORTERRE PATRICK

摘要:The present invention provides an isolated peptide of SEQ ID NO: 1 needed for primase active as well as new replicative DNA polymerase enzymes, preferably that of SEQ ID NO: 2, comprising said peptide. Thus, these DNA polymerases are endowed with priming activity and do not require externally provided primers for initiating and performing DNA amplification. These polymerases are able to carry out a faithful and processive de novo DNA synthesis of DNA templates in the absence of pre-synthetized primers. Therefore, these enzymes of the invention act both as primases and DNA polymerases. Furthermore, they show translesion synthesis capacity, so that they may be useful not only for whole-genome amplification but also for the amplification of damaged DNAs. The invention further refers to methods for amplifying templates DNAs using these enzymes.

标 题 :Control of immune responses by modulating activity of glycosyltransferases
发明人：MARTH JAMEY D; PAULSON JAMES C
权利人:ABARON BIOSCIENCES INC; UNIV CALIFORNIA
摘要:The invention provides methods for inhibiting immune responses by inhibiting the biosynthesis of the sialyl galactosides that are involved in immune responses. In particular, B lymphocyte-mediated immune responses are mediated by interfering with synthesis of α2,6 sialylgalactosides, while T lymphocyte-mediated immune responses are inhibited by blocking synthesis of α2,3 sialylgalactosides. The inhibition is accomplished by, for example, inhibiting the activity of a glycosyltransferase involved in synthesis of the respective sialyl galactoside.
