Disclosed are methods related to identifying an essential gene which serves as an antibiotic target in a bacterium.

Method for identifying antibiotic targets

A system for conducting an assay comprises a power source (), a controller () for controlling the assay and a plurality of assay units () operatively connected to one another such that the controller can communicate with the assay units and the system is capable of conducting the assay. An assay device comprises a substantially circular body () having a plurality of chambers in fluid connection such that fluid can pass between said chambers and a central hub () having a sample inlet () disposed therein for receiving a sample.

Modular assay system

Provided are methods for identifying differentially represented genes, the method comprising the steps of generating a pool of mutant bacteria by transposon mutagenesis with an activating transposon (Tn), wherein the Tncomprises a promoter such that transposon insertion into bacterial DNA increases the transcription of a gene at or near the insertion site; growing bacteria from the mutant pool in the presence of different amounts of said antibiotic to produce two or more test cultures; and comparing the distribution of Tninsertions between test cultures.

Provided herein are methods, and related compositions for identifying a putative essential gene which serves as an antibiotic target in a bacterium, the method, in some embodiments, comprising (a) generating an antibiotic resistant mutant of the bacterium by a method comprising the step of selecting for growth in the presence of an antibiotic to produce an antibiotic resistant mutant clone (Abmutant); (b) transforming the Abmutant with one or more essential genes of the bacterium and a transposon which insertionally inactivates bacterial DNA to produce a pool of transposon mutants which are merodiploid for the one or more essential genes; (c) growing bacteria from the merodiploid pool in the presence of different amounts of the antibiotic to produce two or more test cultures; and (d) comparing the distribution of transposon insertions between the test cultures to identify a putative essential gene serving as a target of the antibiotic in the bacterium.

Method for identifying antibiotic targets by complemented sequencing

The present invention pertains generally to the field of therapeutic compounds, and more specifically to certain bicyclylaryl-aryl-amines compounds of the following formula (referred to herein as BCAA compounds), which, inter alia, inhibit Checkpoint Kinase 1 (CHK1) kinase function. The present invention also pertains to pharmaceutical compositions comprising such compounds, and the use of such compounds and compositions, both in vitro and in vivo, to inhibit CHK1 kinase function, and in the treatment of diseases and conditions that are mediated by CHK1, that are ameliorated by the inhibition of CHK1 kinase function, etc., including proliferative conditions such as cancer, etc., optionally in combination with another agent, for example, (a) a DNA topoisomerase I or II inhibitor; (b) a DNA damaging agent; (c) an antimetabolite or TS inhibitor; (d) a microtubule targeted agent; and (e) ionising radiation: 

Bicyclylaryl-aryl-amine compounds and their use

The present invention pertains generally to the field of therapeutic compounds, and more specifically to certain biarylamine compounds (referred to herein as BAA compounds), and especially certain pyrazin-2-yl-pyridin-2-yl-amine and pyrazine-2-yl-pyrimidin-4-yl-amine compounds, which, inter alia, inhibit Checkpoint Kinase 1 (CHK1) kinase function. The present invention also pertains to pharmaceutical compositions comprising such compounds, and the use of such compounds and compositions, both in vitro and in vivo, to inhibit CHK1 kinase function, and in the treatment of diseases and conditions that are mediated by CHK1, that are ameliorated by the inhibition of CHK1 kinase function, etc., including proliferative conditions such as cancer, etc., optionally in combination with another agent, for example, (a) a DNA topoisomerase I or II inhibitor; (b) a DNA damaging agent; (c) an antimetabolite or TS inhibitor; (d) a microtubule targeted agent; and (e) ionising radiation.
