Dessi, Alessio; Calamante, Massimo; Mordini, Alessandro; Zani, Lorenzo; Taddei, Maurizio; Reginato, Gianna published the artcile< Microwave-activated synthesis of thiazolo[5,4-d]thiazoles by a condensation/oxidation sequence>, Synthetic Route of 1003-32-3, the main research area is thiazolothiazole microwave preparation condensation oxidation.

A microwave-assisted preparation of sym. thiazolo[5,4-d]thiazoles from the corresponding aldehydes is presented. The two-step reaction sequence comprises the condensation of aldehydes with dithiooxamide followed by oxidation/aromatization with 1,4-benzoquinone derivatives The new procedure provides the desired products in good yields and in most cases allows reduction of the excess of aldehyde employed in the process compared to previous methodologies. For the first time, application of the reaction both on aromatic and aliphatic aldehydes is demonstrated.

Pardon, Els; Betti, Cecilia; Laeremans, Toon; Chevillard, Florent; Guillemyn, Karel; Kolb, Peter; Ballet, Steven; Steyaert, Jan published the artcile< Nanobody-Enabled Reverse Pharmacology on G-Protein-Coupled Receptors>, Recommanded Product: 4-(Thiazol-2-yl)benzaldehyde, the main research area is nanobody beta2 adrenoreceptor fusion G protein coupled receptor agonist; GPCRs; drug discovery; fragment screening; inhibitors; nanobodies.

The conformational complexity of transmembrane signaling of G-protein-coupled receptors (GPCRs) is a central hurdle for the design of screens for receptor agonists. In their basal states, GPCRs have lower affinities for agonists compared to their G-protein-bound active state conformations. Moreover, different agonists can stabilize distinct active receptor conformations and do not uniformly activate all cellular signaling pathways linked to a given receptor (agonist bias). Comparative fragment screens were performed on a β2-adrenoreceptor-nanobody fusion locked in its active-state conformation by a G-protein-mimicking nanobody, and the same receptor in its basal-state conformation. This simple biophys. assay allowed the identification and ranking of multiple novel agonists and permitted classification of the efficacy of each hit in agonist, antagonist, or inverse agonist categories, thereby opening doors to nanobody-enabled reverse pharmacol.

Vilaboa, Nuria; Bore, Alba; Martin-Saavedra, Francisco; Bayford, Melanie; Winfield, Natalie; Firth-Clark, Stuart; Kirton, Stewart B.; Voellmy, Richard published the artcile< New inhibitor targeting human transcription factor HSF1: effects on the heat shock response and tumor cell survival>, Category: thiazole, the main research area is human transcription factor HSF1 inhibitor preparation heat shock antitumor.

Comparative modeling of the DNA-binding domain of human HSF1 facilitated the prediction of possible binding pockets for small mols. and definition of corresponding pharmacophores. In silico screening of a large library of lead-like compounds identified a set of compounds that satisfied the pharmacophoric criteria, a selection of which compounds was purchased to populate a biased sublibrary. A discriminating cell-based screening assay identified compound 001, which was subjected to systematic anal. of structure-activity relationships, resulting in the development of compound 115 (IHSF115). IHSF115 bound to an isolated HSF1 DNA binding domain fragment. The compound did not affect heat-induced oligomerization, nuclear localization and specific DNA binding but inhibited the transcriptional activity of human HSF1, interfering with the assembly of ATF1-containing transcription complexes. IHSF115 was employed to probe the human heat shock response at the transcriptome level. In contrast to earlier studies of differential regulation in HSF1-naive and -depleted cells, the authors’ results suggest that a large majority of heat-induced genes is pos. regulated by HSF1. That IHSF115 effectively countermanded repression in a significant fraction of heat-repressed genes suggests that repression of these genes is mediated by transcriptionally active HSF1. IHSF115 is cytotoxic for a variety of human cancer cell lines, multiple myeloma lines consistently exhibiting high sensitivity.
