A minimal cell can be thought of as comprising informational, compartment-forming and metabolic subsystems. To imagine the abiotic assembly of such an overall system, however, places great demands on hypothetical prebiotic chemistry. The perceived differences and incompatibilities between these subsystems have led to the widely held assumption that one or other subsystem must have preceded the others. Here we experimentally investigate the validity of this assumption by examining the assembly of various biomolecular building blocks from prebiotically plausible intermediates and one-carbon feedstock molecules. We show that precursors of ribonucleotides, amino acids and lipids can all be derived by the reductive homologation of hydrogen cyanide and some of its derivatives, and thus that all the cellular subsystems could have arisen simultaneously through common chemistry. The key reaction steps are driven by ultraviolet light, use hydrogen sulfide as the reductant and can be accelerated by Cu(I)âCu(II) photoredox cycling. A minimal cell â one that has all the minimum requirements for life â is still a complex entity comprising informational, compartment-forming and metabolic subsystems. Here it is shown that, contrary to previous assumptions, a common prebiotically plausible chemistry can give rise to building blocks for all the subsystems.
multidrug- and extensively drug-resistant Pseudomonasaeruginosa over recent years have created an urgent need for novel therapeutic approaches to cure potentially fatal infections. One such approach is virulence attenuation where anti-virulence compounds, designed to reduce pathogenicity without affording bactericidal effects, are employed to treat infections. P. aeruginosa uses the pqs quorum sensing (QS)

m-(thiazol-4-yl) benzoic acids substituted in 2- and optionally 5-position of the thiazol ring by lower alkyl, phenylalkyl, phenyl, halo-phenyl, lower alkylphenyl or lower alkoxyphenyl, and on the phenyl ring of the benzoic acid moiety by halogen, hydroxyl, lower alkyl or lower alkoxy. These compounds possess fibrinolytic, platelet stickiness decreasing and antiulcer properties and have an impact on the immunological processes.
