First-in-Human Study of the Ataxia Telangiectasia and Rad3-Related (ATR) Inhibitor Tuvusertib (M1774) as Monotherapy in Patients with Solid Tumors.

Purpose: Tuvusertib (M1774) is a potent, selective, orally administered ataxia telangiectasia and Rad3-related (ATR) protein kinase inhibitor. This first-in-human study (NCT04170153) evaluated safety, tolerability, maximum tolerated dose (MTD), recommended dose for expansion (RDE), pharmacokinetics (PK), pharmacodynamics (PD), and preliminary efficacy of tuvusertib monotherapy.

Patients And Methods: Ascending tuvusertib doses were evaluated in 55 patients with metastatic or locally advanced unresectable solid tumors.

In vitro and in vivo antibacterial evaluation of cadazolid, a new antibiotic for treatment of Clostridium difficile infections.

Clostridium difficile is a leading cause of health care-associated diarrhea with significant morbidity and mortality, and new options for the treatment of C. difficile-associated diarrhea (CDAD) are needed. Cadazolid is a new oxazolidinone-type antibiotic that is currently in clinical development for treatment of CDAD.

Structure-guided design, synthesis and biological evaluation of novel DNA ligase inhibitors with in vitro and in vivo anti-staphylococcal activity.

A series of 2-amino-[1,8]-naphthyridine-3-carboxamides (ANCs) with potent inhibition of bacterial NAD(+)-dependent DNA ligases (LigAs) evolved from a 2,4-diaminopteridine derivative discovered by HTS. The design was guided by several highly resolved X-ray structures of our inhibitors in complex with either Streptococcus pneumoniae or Escherichia coli LigA. The structure-activity-relationship based on the ANC scaffold is discussed.

TNF-alpha and the IFN-gamma-inducible protein 10 (IP-10/CXCL-10) delivered by parvoviral vectors act in synergy to induce antitumor effects in mouse glioblastoma.

Interferon-gamma-inducible protein 10 is a potent chemoattractant for natural killer cells and activated T lymphocytes. It also displays angiostatic properties and some antitumor activity. Tumor necrosis factor-alpha (TNF-alpha) is a powerful immunomodulating cytokine with demonstrated tumoricidal activity in various tumor models and the ability to induce strong immune responses.

Determination of pharmacokinetic parameters in DCE MRI: Consequence of nonlinearity between contrast agent concentration and signal intensity.

Objectives: We sought to compare pharmacokinetic modeling of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) data by assuming a linear and nonlinear relationship between signal intensity (SI) and contrast agent (CA) concentration.

Materials And Methods: Data sets were generated by computer-based simulation studies and DCE-MRI examination of 5 tumor-bearing mice using a 1.5 T MR-scanner.

Evidence for improved performance in cognitive tasks following selective NR2B NMDA receptor antagonist pre-treatment in the rat.

Rationale: We previously reported that the NR2B subunit-selective N-methyl-D-aspartate (NMDA) antagonist Ro 63-1908 produced a marked deficit in response control in the five-choice serial reaction time task (5-CSRTT).

Objectives: The present studies were designed to investigate this further by studying the NR2B NMDA antagonists, ifenprodil, traxoprodil (CP101,606), Ro 25-6981 as well as Ro 63-1908 in this test.

Methods: Following training in the 5-CSRTT, separate groups of rats were either tested under (1) standard test conditions [5 s inter-trial interval (ITI), 0.

The 5-HT2A receptor antagonist M100,907 attenuates motor and 'impulsive-type' behaviours produced by NMDA receptor antagonism.

In the present series of studies, we have investigated the effects of antagonists selective for the 5-HT(2A), 5-HT(2B) and 5-HT(2C) receptors on motor and 'impulsive'-type behaviours elicited by the non-competitive N-methyl- d-aspartate (NMDA) antagonist dizocilpine. The selective 5-HT(2A) receptor antagonist M100,907 (0.5 mg/kg) attenuated the hyperlocomotion and stereotypy produced by dizocilpine (0.

Donepezil reverses a mnemonic deficit produced by scopolamine but not by perforant path lesion or transient cerebral ischaemia.

The purpose of these studies were threefold. Firstly, to further characterize the effect of perforant path transection on a test of short-term memory: delayed matching (or nonmatching)-to-position [D(N)MTP]. Secondly, to evaluate the effect of a transient cerebral ischaemia in the same task.

Audit and quality control in angioplasty in Europe: procedural results of the AQUA Study 1997: assessment of 250 randomly selected coronary interventions performed in 25 centres of five European countries. AQUA Study Group, Nucleus Clinical Issues, Working Group Coronary Circulation, of the European Society of Cardiology.

Aims: Percutaneous transluminal coronary angioplasty (PTCA) has become the most widely used major intervention in western medicine. However, there is disparate use of this technique among different European countries and the U.S.

Clients and therapists confidence and attendance at planned individual therapy sessions.

85 of 217 clients who reported retrospectively that their intake therapist seemed confident of being helpful also reported cancelling and missing fewer follow-up sessions regardless of the length of treatment. Clients' reported confidence during the first session and clients' attendance at later sessions were also associated with three measures of satisfaction with individual therapy.
