    Abstract Delivering new medicines to patients suffering from Neglected Tropical Diseases (NTD) is a major challenge. There are various hurdles to be overcome, such as the large number of patients in a large number of different regions, the lack of marketability, and resistance to medicines. Takeda Pharmaceutical Company Limited (Takeda) is following a corporate mission of "striving towards better health for patients worldwide though leading innovation in medicine". These guiding principles lead to the values of Integrity, Fairness, Honesty and Perseverance that make up what we call "Takeda-ism". As part of its contribution to R&D for NTDs, Takeda collaborates with global Product Development Partnerships (PDPs). In this symposium, the "Drug Discovery Booster" project to accelerate and expand discovery of new drugs for Leishmaniasis and Chagas disease with Drugs for Neglected Diseases initiative (DNDi) and other pharmaceutical companies is introduced. Proprietary compound libraries and the drug discovery expertise of various partners was applied to this new drug discovery approach. An overview of our research projects in malaria, tuberculosis, and NTD is also presented. In addition to these, Takeda's Access to Medicines (ATM) strategy and activities are introduced. Lastly, we discuss a new open innovation model which is accelerated by partnership with a variety of organizations and how Takeda achieves its sustainable development goal (SDG) targets.

    Abstract A series of novel thiazole-containing amides were synthesized. A structure-activity relationship study of these compounds led to the identification of potent and selective PfFPPS/GGPPS inhibitors with good in vitro ADME profiles. The most promising candidate molecules were progressed to mouse in vivo PK studies and demonstrated adequate free drug exposure to warrant further investigation.

    Abstract Background: The current pipeline for new antibiotics fails to fully address the significant threat posed by drug-resistant Gram-negative bacteria that have been identified by the World Health Organization (WHO) as a global health priority. New antibacterials acting through novel mechanisms of action are urgently needed. We aimed to identify new chemical entities (NCEs) with activity against Klebsiella pneumoniae and Acinetobacter baumannii that could be developed into a new treatment for drug-resistant infections.
    Methods: We developed a high-throughput phenotypic screen and selection cascade for generation of hit compounds active against multidrug-resistant (MDR) strains of K. pneumoniae and A. baumannii. We screened compound libraries selected from the proprietary collections of three pharmaceutical companies that had exited antibacterial drug discovery but continued to accumulate new compounds to their collection. Compounds from two out of three libraries were selected using "eNTRy rules" criteria associated with increased likelihood of intracellular accumulation in Escherichia coli.
    Findings: We identified 72 compounds with confirmed activity against K. pneumoniae and/or drug-resistant A. baumannii. Two new chemical series with activity against XDR A. baumannii were identified meeting our criteria of potency (EC
    Interpretation: This work provides proof of principle for the screening strategy developed to identify NCEs with antibacterial activity against multidrug-resistant critical priority pathogens such as K. pneumoniae and A. baumannii. The screening and hit selection cascade established here provide an excellent foundation for further screening of new compound libraries to identify high quality starting points for new antibacterial lead generation projects.

  4. Article ; Online: Phosphorus ligands with a large cavity: synthesis of triethynylphosphines with bulky end caps and application to the rhodium-catalyzed hydrosilylation of ketones.

    Abstract: Trialkynylphosphines substituted with bulky triarylsilyl groups at the alkyne termini were synthesized. The new phosphines P(C[triple chemical bond]CSiAr(3))(3) (Ar=3,5-tBu(2)-4-MeOC(6)H(2), 3,5-(Me(3)Si)(2)C(6)H(3)) are uncrowded near the phosphorus ... ...

    Abstract Trialkynylphosphines substituted with bulky triarylsilyl groups at the alkyne termini were synthesized. The new phosphines P(C[triple chemical bond]CSiAr(3))(3) (Ar=3,5-tBu(2)-4-MeOC(6)H(2), 3,5-(Me(3)Si)(2)C(6)H(3)) are uncrowded near the phosphorus atom but bulky in the distal region. As a result, they contain a large cavity, at the bottom of which the phosphine lone-pair electrons are located. The compounds are stable to oxidation by air and hydrolysis. DFT calculations suggested that the triethynylphosphines are good pi-acceptor ligands, comparable with P(OAr)(3). The trialkynylphosphines reacted with [{RhCl(cod)}(2)] (P/Rh=1.1:1) to give selectively the monophosphine-rhodium complex [RhCl(cod)P(C[triple chemical bond]CSiAr(3))(3)]. X-ray crystal-structure analysis revealed that the {RhCl(cod)} fragment is fully accommodated by the cavity of the phosphine ligand. Compared to the effect of analogues with smaller end caps and PPh(3), the trialkynylphosphines accelerated markedly the rhodium-catalyzed hydrosilylation of ketones with a triorganosilane. It is proposed that the higher catalytic activity observed with the holey phosphines is a result of the preferential formation of a monophosphine-rhodium species.

    Abstract Background/aims: Retinoid-related orphan receptor gamma t (RORγt) is a master regulator of T helper 17 cells that plays a pivotal role in the production of inflammatory cytokines including interleukin (IL)-17. Therefore, RORγt has attracted much attention as a target receptor for the treatment of inflammatory diseases including rheumatoid arthritis, multiple sclerosis, inflammatory bowel diseases, and psoriasis. This study aims to characterize TAK-828F, a potent and selective RORγt inverse agonist.
    Methods: The biochemical properties of TAK-828F were evaluated using Time-Resolved Fluorescence Resonance Energy Transfer (TR-FRET) binding assay, surface plasmon resonance (SPR) biosensor assay, cofactor recruitment assay, reporter assay, and IL-17 expression assay.
    Results: TR-FRET binding assay and SPR biosensor assay revealed rapid, reversible, and high affinity binding of TAK-828F to RORγt. The cofactor recruitment assay showed that TAK-828F inhibited the recruitment of steroid receptor coactivator-1 to RORγt. Furthermore, TAK-828F inhibited the transcriptional activity of human and mouse RORγt with selectivity against human RORα and RORβ. TAK-828F also suppressed IL-17 production in Jurkat cells, overexpressing human RORγt.
    Conclusion: These favorable properties will be of advantage in the evaluation of TAK-828F in clinical studies for inflammatory diseases. Furthermore, these findings demonstrate that TAK-828F could serve as a pharmacological tool for further studies of RORγt and inflammatory diseases.
