Seven novel 5-substituted phenylthiazole oxadiazolethiones: [Me-PTOT(H)], [MeO-PTOT(H)], [MeS-PTOT(H)], [F-PTOT(H)], [Cl-PTOT(H)], [Br-PTOT(H)], and [CF3-PTOT(H)], {where X-PTOT(H) = 5-[2-(4-X)thiazol-4-yl]-1,3,4-oxadiazole-2(3H)-thione, 4-X = C6H4}, were synthesised from their corresponding thioamides. From these seven heteroleptic thiolatobismuth complexes: BiPh(Me-PTOT)2 6, BiPh(MeO-PTOT)2 7, BiPh(MeS-PTOT)2 8, BiPh(F-PTOT)2 9, BiPh(Cl-PTOT)2 10, BiPh(Br-PTOT)2 11 and BiPh(CF3-PTOT)2 12 were synthesised and characterised. Complexes [10(DMSO)2] and [11(DMSO)2] were structurally characterised using X-ray diffraction. Evaluation of the antibacterial properties of the thiones and their BiIII complexes against Mycobacterium smegmatis, Staphylococcus aureus (S. aureus), Methicillin-resistant Staphylococcus aureus (MRSA), Vancomycin-resistant Enterococcus (VRE), Enterococcus faecalis (E. faecalis) and Escherichia coli (E. coli) showed that all bismuth(III) complexes were highly effective against all the bacteria, as demonstrated by very low MIC values (1.1-2.1 μM). Complexes BiPh(Me-PTOT)2 6, BiPh(Cl-PTOT)2 10 and BiPh(Br-PTOT)2 11, showed best activity against the multi-drug resistant bacteria VRE and MRSA with an MIC value of 1.0 μM. All these complexes and their corresponding thiones failed to show any prominent activity against M. smegmatis and E. coli, even at high concentrations. These complexes showed little or no toxicity towards mammalian COS-7 cells at 20 μg/mL. Seven heteroleptic thiolatobismuth(III) complexes [BiPh(X-PTOT)2] derived from a series of 5-substituted phenylthiazole oxadiazolethiones [X-PTOT(H)] provide powerful antibacterial action against the multi-resistant bacteria MRSA and VRE.

A novel series of 4-phenyl-5-pyridyl-1,3-thiazole analogues possessing potent in vitro inhibitory activity against p38 mitogen-activated protein kinase and the release of tumor necrosis factor-α (TNF-α) from human monocytic THP-1 cells stimulated by lipopolysaccharide has been identified. Subsequent structure-activity relationship (SAR) studies and optimization for absorption, distribution, metabolism, and elimination (ADME) profiles led to the identification of compounds 7g and 10b as orally active lead candidates that block the in vivo production of proinflammatory cytokine (TNF-α). In pharmacokinetic studies, compound 10b showed good oral administration in mice and demonstrated significant in vivo anti-inflammatory activity in an anti-collagen monoclonal antibody-induced arthritis mouse model (minimum effective dose (MED)=30 mg/kg). Further elucidation of this class of compounds may provide novel anti-inflammatory agents, such as anti-rheumatoid arthritis drugs.
