Kumar A, Kumar V, Ojha PK, Roy K. Chronic aquatic toxicity assessment of diverse chemicals on Daphnia magna using QSAR and chemical read-across. Regul Toxicol Pharmacol 2024; 148:105572. [PMID: 38325631 DOI: 10.1016/j.yrtph.2024.105572] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2023] [Revised: 01/06/2024] [Accepted: 01/26/2024] [Indexed: 02/09/2024]
Abstract
We have modeled here chronic Daphnia toxicity taking pNOEC (negative logarithm of no observed effect concentration in mM) and pEC50 (negative logarithm of half-maximal effective concentration in mM) as endpoints using QSAR and chemical read-across approaches. The QSAR models were developed by strictly obeying the OECD guidelines and were found to be reliable, predictive, accurate, and robust. From the selected features in the developed models, we have found that an increase in lipophilicity and saturation, the presence of electrophilic or electronegative or heavy atoms, the presence of sulphur, amine, and their related functionality, an increase in mean atomic polarizability, and higher number of (thio-) carbamates (aromatic) groups are responsible for chronic toxicity. Therefore, this information might be useful for the development of environmentally friendly and safer chemicals and data-gap filling as well as reducing the use of identified toxic chemicals which have chronic toxic effects on aquatic ecosystems. Approved classes of drugs from DrugBank databases and diverse groups of chemicals from the Chemical and Product Categories (CPDat) database were also assessed through the developed models.

CYP1A2 and tobacco interaction: a major pharmacokinetic challenge during smoking cessation. Drug Metab Rev 2021; 53:30-44.

Abstract
Smoking cessation is underestimated in terms of drug interactions. Abrupt smoking cessation is common in cases of emergency hospitalization and restrictions of movement. Tobacco is a known cytochrome P450 1A2 (CYP1A2) inducer, its consumption and withdrawal can lead to major pharmacokinetic drug interactions. Nevertheless, references do exist, but may have different results between them. The objective of our work was to establish the broadest and most consensual list as possible of CYP1A2 substrates treatments and propose a pharmacological approach. We searched the widest possible list of CYP1A2 substrates based on various international references. We compared the references and defined probability and reliability scores of our results to sort the substances based on the scores. For the 245 substances identified as CYP1A2 substrates, we focused on the 63 CYP1A2 substrates with both probability and reliability scores >50%. Our work establishes adaptive pharmacological approaches for the management of patients initiating smoking cessation which must be integrated into the management of smoking cessation. Pharmacologists can now adopt adaptive pharmacological approaches to complement patient-specific clinical information about smoking cessation by considering pharmacokinetic risk. This work establishes an unprecedented list. It should guide in the care of patients initiating smoking cessation to prevent pharmacokinetic drug interactions.
