A novel tyrosyl diester antibiotic is obtained from fermentation of a recombinant strain of,designated,WD 15684 (ATCC-202143). The new antibiotic, designated tyrissamycin, exhibits antibacterial activity, particularly against gram-positive bacteria.

Tyrissamycin antibiotic

The present invention relates to a novel drug discovery system for generating molecular diversity. The system provides methods for subjecting the genetic materials from a plurality of species of organisms to homologous or homeologous recombination to create novel genes and metabolic pathways. The recombined genetic materials are cloned to form recombined combinatorial gene expression libraries. Methods for screening such gene expression libraries containing recombined genes and metabolic pathways for novel activities and compounds are also provided.

Methods for generating and screening novel metabolic pathways

The present invention features compounds and methods for inhibiting propagation of human immunodeficiency virus (HIV). Preferred HIV target sites are identified and oligonucleotides designed to hybridize to a target site are described. The preferred use of the oligonucleotides is as an anti-HIV agent to inhibit HIV propagation in a patient infected with HIV. Other uses of the present invention include detecting the presence of HIV by using the oligonucleotides as detection probes or amplification primers, and measuring the ability of an oligonucleotide to inhibit HIV propagation to evaluate its suitability as an anti-HIV agent for a phenotype of HIV or diagnose the presence of HIV in a patient.

The present invention relates to a novel drug discovery system for generating and screening molecular diversity. The system provides methods for mixing and cloning genetic materials from a plurality of species of organisms in combinatorial gene expression libraries to generate novel metabolic pathways and classes of compounds. The system also involves methods for pre-screening or identifying for host organisms containing a library that are capable of generating such novel pathways and compounds. The host organisms may be useful in drug screening for particular diseases, and in commercial production of compounds of interest. The methods of the invention are also useful in preserving the genomes of organisms that are known or prospective sources of drugs.

The present invention relates to a novel drug discovery system for generating and screening molecular diversity. The system provides methods for mixing and cloning genetic materials from a plurality of species of organisms in combinatorial gene expression libraries to generate novel metabolic pathways and classes of compounds. The system also provides mobilizable combinatorial gene expression libraries that can be transferred from one species of host organism to another for expression. Also provided are specialized cloning vectors for making mobilizable gene expression libraries. The system also involves methods for pre-screening or identifying for host organisms containing a library that are capable of generating such novel pathways and compounds.
