Published: January 2004

Structural optimization of pyrazolopyridine derivative 2, which is one of the newly discovered chemical leads for PDE4 inhibitors from our in-house library, was carried out successfully. The process of discovery of new orally active PDE4 inhibitors, which are expected to possess therapeutic potential, is presented and their structure-activity relationships are discussed.

Introduction: Fungi, including , may be a trigger or exacerbate psoriasis, especially in difficult to treat (DTT) areas, through the activation of IL-17/23 axis.

Methods: In this study, seventy patients with DDT psoriasis were enrolled to evaluate species and/or other opportunistic fungi colonization rate at baseline (T0) and the impact of apremilast on fungal load, clinical outcome, serum cytokine levels and biochemical serum profile of patients after 16, 24 and 52 weeks of treatment.

Results: In our population, 33 (47%) patients were colonized by spp.

Interstitial lung disease (ILD) associated with rheumatoid arthritis or with connective tissue diseases such as systemic sclerosis can be collectively named systemic autoimmune rheumatic disease-associated ILDs (SARD-ILDs) or rheumatic musculoskeletal disorder-associated ILDs. SARD-ILDs result in substantial morbidity and mortality, and there is a high medical need for effective therapies that target both fibrotic and inflammatory pathways in SARD-ILD. Phosphodiesterase 4 (PDE4) hydrolyses cyclic AMP, which regulates multiple pathways involved in inflammatory processes.

Objectives: To investigate which phosphodiesterase (PDE) isoforms are expressed in fibroblasts isolated from the tunica albuginea (TA) of patients with Peyronie's disease (PD), and to measure the potency of PDE inhibitors in preventing transformation of these fibroblasts to profibrotic myofibroblasts.

Materials And Methods: Fibroblasts isolated from the TA of men undergoing surgery for correction of PD curvature were transformed to myofibroblasts using transforming growth factor beta-1. The expression of 21 PDE isoforms was investigated using quantitative reverse transcriptase-polymerase chain reaction and protein analysis, as were the effects of various PDE inhibitors on prevention of myofibroblast transformation.

Background: We evaluated the efficacy and safety of Ensifentrine in COPD via a systematic review and meta-analysis of randomized controlled trials (RCTs).

Methods: We performed a detailed literature search on Medline (via PubMed), Scopus, Google Scholar, and Cochrane on the basis of pre-specified eligibility criteria. We used Review Manager to calculate pooled mean differences (MD) and 95% Confidence Interval (CI) using a random effects model.
