    摘要： Seryl-lysyl-based peptide and peptidomimetic compounds are described as inhibitors of the enzyme N-myristoyl transferase to provide selective control of the fungal organism Candida albicans. Peptidomimetic compounds of particular interest are those of the formula: wherein R1 is selected form aminoalkyl, p-aminoalkylphenylalkyl, imidazolylalkylphenylalkyl, 2-alkylimidazolylalkylphenylalkyl, benzimidazolylalkylphenylalkyl and 2-alkylbenzimidazolylalkylphenylalkyl; wherein R2 is selected from hydrido, alkyl, cycloalkyl, akenyl, alkynyl, haloalkyl, benzyl, alkylphenylalkyl, alkoxyphenylalkyl, halophenylalkyl, phenethyl, cycloalkylalkyl, halocycloalkylalkyl, alkylcycloalkylalkyl, alkoxycycloalkylalkyl and naphthylalkyl; wherein Y is selected from carboxylic acid, hydroxamic acid, phosphonic acid and tetrazolyl; or a pharmaceutically-acceptable salt, amide or ester thereof. Compounds of the formula are species-specific inhibitors of C. albicans with little effect on human NMT enzyme and thus would.be useful in treating C. albicans fungal infections in humans.

    摘要： Disclosed are transgenic mice that produces prostate tumors and faithfully recapitulate many of the features of human prostatic carcinoma. It has been discovered that transcriptional regulatory elements active in Paneth cells, granule goblet cells, intermediate cells, or a combination, when used to express Simian Virus 40 large T antigen (TAg) in a transgenic mouse leads to development of prostate tumors in the mouse. The transcriptional regulatory elements are derived from the cryptdin-2 (CR2) gene. The disclosed mice develop prostatic intraepithelial neoplasia (PIN) at an early age. Progression with local invasion, loss of androgen-dependence and eventual metastases are hallmarks of the disclosed transgenic mice. Preferred embodiments of the disclosed transgenic mice have several important characteristics: (1) the disease is fully penetrant--all mice containing the SV40 TAg transgene develop prostatic cancer; (2) the first appearance of SV40 TAg always coincides with the appearance of cellular atypia in prostatic acini; (3) the rate of progression of the neoplasia is rapid; (4) prostatic adenocarcinomas in the transgenic mice exhibit foci of neuroendocrine differentiation; (5) metastatic lesions are common in the lymph nodes, liver, lung, and bone of the disclosed transgenic mice and are evident early in life; and (6) the lifespan of the disclosed transgenic animals is not shortened by transgene-related pathology in other organs--female transgenic mice develop normally and have a normal lifespan.

    摘要： There is disclosed a method for providing for the coexpression of N-myristoyltransferase and a protein substrate for said N-myristoyltransferase in E. coli comprising introducing into E. coli a dual plasmid system comprising (A) the isopropyl-.beta.-D-thiogalactopyranoside-inducible tac promoter, the g10-L ribosome binding site, a NMT gene, the kanamycin resistance gene and the p15A origin of replication in operable sequence and (B) the recA promoter, the g10-L ribosome binding site, a mammalian gene, the ampicillin resistance gene and the Col E1 origin of replication in operable sequence. This allows production of mammalian N-myristoylproteins or proteins containing covalently linked analogs of myristate with altered physical-chemical properties.
