Thiocillin I is an antibiotic originally isolated from Bacillus that has activity against Gram-positive, but not Gram-negative, bacteria. It inhibits the growth of B. subtilis, B. anthracis, S. aureus, S. pyogenes, and S. pneumoniae strains in vitro (MICs = 0.2-3.13 μg/ml). Thiocillin I exhibits antibiotic activity in a mouse model of S. pyogenes infection (ED50 = 2.91 mg/kg).

Total synthesis of micrococcin P1 and Thiocillin I enabled by Mo(vi) catalyst
Chem Sci 2018 Dec 3;10(7):1971-1975.PMID:30881626DOI:10.1039/c8sc04885a.
Thiopeptides are a class of potent antibiotics with promising therapeutic potential. We developed a novel Mo(vi)-oxide/picolinic acid catalyst for the cyclodehydration of cysteine peptides to form thiazoline heterocycles. With this powerful tool in hand, we completed the total syntheses of two representative thiopeptide antibiotics: micrococcin P1 and Thiocillin I. These two concise syntheses (15 steps, longest linear sequence) feature a C-H activation strategy to install the trisubstituted pyridine core and thiazole groups. The synthetic material displays promising antimicrobial properties measured against a series of Gram-positive bacteria.
Dynamic interspecies interactions and robustness in a four-species model biofilm
Microbiologyopen 2021 Nov;10(6):e1254.PMID:34964290DOI:10.1002/mbo3.1254.
Interspecific interactions within biofilms determine relative species abundance, growth dynamics, community resilience, and success or failure of invasion by an extraneous organism. However, deciphering interspecific interactions and assessing their contribution to biofilm properties and function remain a challenge. Here, we describe the constitution of a model biofilm composed of four bacterial species belonging to four different genera (Rhodocyclus sp., Pseudomonas fluorescens, Kocuria varians, and Bacillus cereus), derived from a biofilm isolated from an industrial milk pasteurization unit. We demonstrate that the growth dynamics and equilibrium composition of this biofilm are highly reproducible. Based on its equilibrium composition, we show that the establishment of this four-species biofilm is highly robust against initial, transient perturbations but less so towards continuous perturbations. By comparing biofilms formed from different numbers and combinations of the constituent species and by fitting a growth model to the experimental data, we reveal a network of dynamic, positive, and negative interactions that determine the final composition of the biofilm. Furthermore, we reveal that the molecular determinant of one negative interaction is the Thiocillin I synthesized by the B. cereus strain, and demonstrate its importance for species distribution and its impact on robustness by mutational analysis of the biofilm ecosystem.
Total synthesis and complete structural assignment of Thiocillin I

The total synthesis of the thiopeptide antibiotic, Thiocillin I, is described. This work unequivocally defines the full structure (constitution and configuration) of the natural product as 1.
Thiopeptide biosynthesis featuring ribosomally synthesized precursor peptides and conserved posttranslational modifications
Chem Biol 2009 Feb 27;16(2):141-7.PMID:19246004DOI:10.1016/j.chembiol.2009.01.007.
Thiopeptides, with potent activity against various drug-resistant pathogens, contain a characteristic macrocyclic core consisting of multiple thiazoles, dehydroamino acids, and a 6-membered nitrogen heterocycle. Their biosynthetic pathways remain elusive, in spite of great efforts by in vivo feeding experiments. Here, cloning, sequencing, and characterization of the thiostrepton and siomycin A gene clusters unveiled a biosynthetic paradigm for the thiopeptide specific core formation, featuring ribosomally synthesized precursor peptides and conserved posttranslational modifications. The paradigm generality for thiopeptide biosynthesis was supported by genome mining and ultimate confirmation of the Thiocillin I production in Bacillus cereus ATCC 14579, a strain that was previously unknown as a thiopeptide producer. These findings set the stage to accelerate the discovery of thiopeptides by prediction at the genetic level and to generate structural diversity by applying combinatorial biosynthesis methods.
