Microbial infections remain a worldwide leading cause of death, despite the evolution of a large number of new antibiotics every year. Currently, several bacteria have developed resistance against antibiotics drugs which remain a major issue in antibiotics drug discovery. This review provides detailed information about antimicrobial and antifungal agent synthesis belonging to the pyrazoles scaffold. We reassemble the results obtained from several studies to characterize the importance of heteroatom nuclei in many synthetic products. Additionally, several compounds based on pyrazole derivatives such as benzimidazole, benzothiazole, indole, acridine, oxadiazole, imidazole, isoxazole, pyrazole, triazole, quinoline and quinazoline including other pyrazole containing drugs such as pyridazine, pyridine and pyrimidine are highlighted. Furthermore, you will find in this review 134 best promise structures collected from recent studies, relating the pyrazoles structures to the relevant biological activities, in particular, antimicrobial and antifungal one.

Purpose: A recent update of consensus guidelines for the management of Cushing's disease (CD) included indications for medical therapy. However, there is limited evidence regarding their implementation in clinical practice. This study aimed to evaluate current medical therapy approaches by expert pituitary centers through an audit conducted to validate the criteria of Pituitary Tumors Centers of Excellence (PTCOEs) and provide an initial standard of medical care for CD.

We report on a fatal case of invasive fungal rhinosinusitis with after lung transplantation. After endoscopic treatment and adjuvant medical therapy with isavuconazole, caspofungin and an investigational antifungal drug, there was a good clinical response with absence of endoscopic and radiographic disease. However, the patient developed disease recurrence, with signs of intracranial involvement on MRI, for which urgent endoscopic sinus surgery was performed and isavuconazole was restarted.

Introduction: Graft-versus-host disease (GvHD) remains a major complication of allogeneic stem cell transplantation (allo-SCT), affecting 30-70% of patients (representing 800 new patients per year in the UK). The risk is higher in patients undergoing unrelated allo-SCT. About 1 in 10 patients die as a result of GvHD or through complications of its treatment.

Anti-infective agents are a class of drugs used to prevent, treat, or control infections caused by microorganisms such as bacteria, viruses, fungi, and parasites. They play a crucial role in modern medicine, helping to reduce the severity of infections and, in many cases, save lives. This study aims at the design and synthesis of hybrid compounds containing quinoxaline, pyrrolidine, and an azo bridge to combat antimicrobial resistance, and evaluating their antimicrobial, antifungal, and antiviral activities against various pathogenic strains.
