Lithiation of 4-membered heterocycles as useful strategy for the preparation of new molecular scaffolds: addressing the regioselectivity in azetidines and thietanes [PDF]

open access: yes, 2013
Four-membered heterocycles (4-MH) with one or two heteroatoms are of great importance in medicinal chemistry and synthetic organic chemistry. This kind of scaffolds show peculiar structural features, related to the ring “puckering”, and biological ...

A Unified Monte Carlo Treatment of Gas-Grain Chemistry for Large Reaction Networks. II. A Multiphase Gas-Surface-Layered Bulk Model

open access: yes, 2012
The observed gas-phase molecular inventory of hot cores is believed to be significantly impacted by the products of chemistry in interstellar ices. In this study, we report the construction of a full macroscopic Monte Carlo model of both the gas-phase ...

Cyclic nucleotide signaling as a drug target in retinitis pigmentosa

open access: yesFEBS Letters, EarlyView.
Disruptions in cGMP and cAMP signaling can contribute to retinal dysfunction and photoreceptor loss in retinitis pigmentosa. This perspective examines the mechanisms and evaluates emerging evidence on targeting these pathways as a potential therapeutic strategy to slow or prevent retinal degeneration.

The epithelial barrier theory proposes a comprehensive explanation for the origins of allergic and other chronic noncommunicable diseases

open access: yesFEBS Letters, EarlyView.
Exposure to common noxious agents (1), including allergens, pollutants, and micro‐nanoplastics, can cause epithelial barrier damage (2) in our body's protective linings. This may trigger an immune response to our microbiome (3). The epithelial barrier theory explains how this process can lead to chronic noncommunicable diseases (4) affecting organs ...

Interdisciplinary Research-Based Learning in Organic Chemistry and Microbiology Laboratories: Synthesis and Biological Testing of Novel Penicillin Derivatives [PDF]

open access: yes, 2015
Interests in the mechanism that penicillin bestows on its target protein has driven the curiosity of its binding specificity towards the methicillin resistant strain of Staphylococcus areus, and its expression of a unique penicillin binding protein that ...

Morley's “Organic Chemistry” [PDF]

open access: yesNature, 1886
THE faults into which the writer of a text-book of organic chemistry for students is apt to be led are, as Dr. Morley points out in his preface, that of overelaboration on the one hand, to which the material too readily lends itself, and that of unintelligent abridgment on the other. Dr.

Titan's Organic Chemistry [PDF]

open access: yesSymposium - International Astronomical Union, 1985
Voyager discovered nine simple organic molecules in the atmosphere of Titan. Complex organic solids, called tholins, produced by irradiation of simulated Titanian atmosphere are consistent with measured properties of Titan from ultraviolet to microwave frequencies, and are the likely main constituents of the observed red aerosols.
