Design and synthesis of novel 8-(azaindolyl)-benzoazepinones as potent and selective ROCK inhibitors.

We report the characterization of potent and selective ROCK inhibitors identified through a core-hopping strategy. A virtual screening workflow, combining ligand- and structure-based methods, was applied on a known series of ROCK inhibitors bearing an acetamido-thiazole scaffold. The most promising replacement of the central core was represented by a benzoazepinone ring, which was selected as a starting point for a subsequent chemical exploration.

Discovery, Multiparametric Optimization, and Solid-State Driven Identification of CHF-6550, a Novel Soft Dual Pharmacology Muscarinic Antagonist and β Agonist (MABA) for the Inhaled Treatment of Respiratory Diseases.

Clinical guidelines for COPD and asthma recommend inhaled β-adrenergic agonists, muscarinic antagonists, and, for frequent exacerbators, inhaled corticosteroids, with the challenge of combining them into a single device. The MABA (muscarinic antagonist and β agonist) concept has the potential to simplify this complexity while increasing the efficacy of both pharmacologies. In this article, we report the outcome of our solid-state driven back-up program that led to the discovery of the MABA compound .

Application of an "inhalation by design" approach to the identification and in-vitro evaluation of novel purine based PI3Kδ inhibitors.

PI3Kδ is a lipid kinase which plays a key role in airway inflammatory conditions. Accordingly, the inhibition of PI3Kδ can be considered a valuable strategy for the treatment of chronic respiratory diseases such as Asthma and Chronic obstructive pulmonary disease (COPD). In this work, we describe our efforts to identify new PI3Kδ inhibitors following an "inhalation by design" strategy.

Discovery of Clinical Candidate CHF-6366: A Novel Super-soft Dual Pharmacology Muscarinic Antagonist and β Agonist (MABA) for the Inhaled Treatment of Respiratory Diseases.

The development of molecules embedding two distinct pharmacophores acting as muscarinic antagonists and β agonists (MABAs) promises to be an excellent opportunity to reduce formulation issues and boost efficacy through cross-talk and allosteric interactions. Herein, we report the results of our drug discovery campaign aimed at improving the therapeutic index of a previous MABA series by exploiting the super soft-drug concept. The incorporation of a metabolic liability, stable at the site of administration but undergoing rapid systemic metabolism, to generate poorly active and quickly eliminated fragments was pursued.

Discovery of a novel class of inhaled dual pharmacology muscarinic antagonist and β agonist (MABA) for the treatment of chronic obstructive pulmonary disease (COPD).

The targeting of both the muscarinic and β-adrenergic pathways is a well validated therapeutic approach for the treatment of chronic obstructive pulmonary disease (COPD). In this communication we report our effort to incorporate two pharmacologies into a single chemical entity, whose characteristic must be suitable for a once daily inhaled administration. Contextually, we aimed at a locally acting therapy with limited systemic absorption to minimize side effects.

Mental and physical health in family members of substance users: A scoping review.

Background: Due to the high pressure they sustain, family members of substance users are thought to experience negative consequences in mental and physical health. This scoping review provided a comprehensive overview on the mental and physical health of adult Affected Family Members (AFMs).

Method: We searched in-journal English articles in PubMed, with no date limit, guided by the concepts of stress, strain, and burden, and including several terms related to substance use.

Novel Pyrrolidine Derivatives of Budesonide as Long Acting Inhaled Corticosteroids for the Treatment of Pulmonary Inflammatory Diseases.

Inhaled corticosteroids (ICSs) represent the first line therapy for the treatment of asthma and are also extensively utilized in chronic obstructive pulmonary disease. Our goal was to develop a new ICS with a basic group, which can allow solid state feature modulation, achieving at the same time high local anti-inflammatory effect and low systemic exposure. Through a rational drug design approach, a new series of pyrrolidine derivatives of budesonide was identified.

Discovery of potent and selective matrix metalloprotease 12 inhibitors for the potential treatment of chronic obstructive pulmonary disease (COPD).

Chronic obstructive pulmonary disease (COPD) is an inflammatory lung disease associated with irreversible progressive airflow limitation. Matrix metalloproteinase-12 (MMP-12) has been characterized to be one of the major proteolytic enzymes to induce airway remodeling, destruction of elastin and the aberrant remodeling of damaged alveoli in COPD and asthma. The goal of this project is to develop and identify an orally potent and selective small molecule inhibitor of MMP-12 for treatment of COPD and asthma.

Identification of an orally efficacious matrix metalloprotease 12 inhibitor for potential treatment of asthma.

MMP-12 plays a significant role in airway inflammation and remodeling. Increased expression and production of MMP-12 have been observed in the lungs of asthmatic patients. Compound 27 was identified as a potent and selective MMP-12 inhibitor possessing good physicochemical properties.
