Average body temperature dropped every decade since the 1800s and even more every decade since 1960Â
Attention, fellow humans! It’s time to chill out… literally! đ§ Our bodies are on a cosmic cooldown, and it’s not just because we’ve all become walking popsicles addicted to air conditioning. Oh no, this is far more sinister and hilarious than that! The Great American Refrigerationâïž Since the 1800s, our core temperatures have been dropping…

Intrauterine Exposure to Paracetamol and Aniline Impairs Female Reproductive Development by Reducing Follicle Reserves and Fertility
Studies report that fetal exposure to paracetamol/acetaminophen by maternal consumption can interfere with male reproductive development. Moreover, recent biomonitoring data report widespread presence of paracetamol in German and Danish populations, suggesting exposure via secondary (nonpharmaceutical) sources, such as metabolic conversion from the ubiquitous industrial compound aniline. In this study, we investigated the extent to which…

Glucuronic acid is a uronic acid that was first isolated from urine
Glucuronic acid (from Greek γλΔῊÎșÎżÏ “wine, must” and ÎżáœÏÎżÎœ “urine“) is a uronic acid that was first isolated from urine (hence the name”uronic acid”). It is found in many gums such as gum arabic (approx. 18%), xanthan, and kombucha tea and is important for the metabolism of microorganisms, plants and animals. Not to be confused with Gluconic acid (Gluconic acid occurs naturally in fruit, honey, and wine. As a food additive E574, it is now known as an acidity regulator.…

Enterohepatic circulation
Enterohepatic circulation refers to the circulation of biliary acids, bilirubin, drugs or other substances from the liver to the bile, followed by entry into the small intestine, absorption by the enterocyte and transport back to the liver. Enterohepatic circulation is an especially important concept in the field of toxicology as many lipophilic xenobiotics undergo this process causing repeated liver damage. Enterohepatic circulation allows for recycling of metabolized and non-metabolized compounds,…

Piceol is a phenolic compound found in the needles and in mycorrhizal roots of Norway spruces and more
Piceol is a phenolic compound found in the needles and in mycorrhizal roots of Norway spruces (Picea abies). Picein is the glucoside of piceol. Pungenin is a also phenolic compound found in the needles of Blue Spruce (Picea pungens). It is the glucoside of 3,4-dihydroxyacetophenone. The compound serves a feeding deterrent against Spruce Budworm larvae. This may be a little redundant as the base information is already included on the Baccharis page…

Baccharis is a genus of perennials and shrubs in the aster family (Asteraceae)
They are commonly known as baccharises but sometimes referred to as “brooms”, because many members have small thin leaves resembling the true brooms. They are not at all related to these however, but belong to an entirely different lineage of eudicots. B. halimifolia is commonly known as “groundsel bush”, however true groundsels are found in the genus Senecio. Baccharis, with over 500…

Interactions between Paracetamol and Formaldehyde: Theoretical Investigation and Topological Analysis (Abstract and References)
In this work, noncovalent interactions including hydrogen bonds, C···C, N···O, and van der Waals forces between paracetamol and formaldehyde were investigated using the second-order perturbation theory MP2 in conjunction with the correlation consistent basis sets (aug-cc-pVDZ and aug-cc-pVTZ). Two molecular conformations of paracetamol were considered. Seven equilibrium geometries of dimers were found from the result…

Pi stacking aka ÏâÏ stacking
In chemistry, pi stacking (also called ÏâÏ stacking) refers to the presumptive attractive, noncovalent pi interactions (orbital overlap) between the pi bonds of aromatic rings. However this is a misleading description of the phenomena since direct stacking of aromatic rings (the “sandwich interaction”) is electrostatically repulsive. What is more commonly observed (see figure below) is either a staggered stacking (parallel displaced) or pi-teeing (perpendicular T-shaped) interaction both of which are electrostatic attractive For…

AM404, aka N-arachidonoylphenolamine, is an active metabolite of paracetamolÂ
AM404, also known as N-arachidonoylphenolamine, is an active metabolite of paracetamol (acetaminophen), responsible for all or part of its analgesic action and anticonvulsant effects. Chemically, it is the amide formed from 4-aminophenol and arachidonic acid. Pharmacology It is established that AM404 increases concentrations of the endogenous cannabinoid anandamide within the synaptic cleft, contributing to its analgesic activity. This has been well characterised as involving endocannabinoid transporter inhibition, but the precise transporter responsible is yet to be…

4-Aminophenol – what a molecule!
This is a humble organic compound with the formula H2NC6H4OH, but donât let its unassuming structure fool you. This is not just any crystalline powder; this is a chemical that moonlights as a pharmaceutical ingredient, a hair dye precursor, andâwait for itâa black-and-white film developer. If molecules had rĂ©sumĂ©s, 4-Aminophenolâs would read like someone whoâs worked…

Paracetamol is an aniline derivative with a sketchy date of birth (and a very sketchy rebirth)
Paracetamol was first made in 1877…or possibly 1852. Some reports state that Cahn & Hepp or a French chemist called Charles Gerhardt first synthesized paracetamol in 1852. Acetanilide was the first aniline derivative serendipitously found to possess analgesic as well as antipyretic properties, and was quickly introduced into medical practice under the name of Antifebrin by Cahn & Hepp in 1886. But…

Paracetamol is extremely toxic to cats, which lack the necessary UGT1A6 enzyme to detoxify it
Paracetamol is extremely toxic to cats, which lack the necessary UGT1A6 enzyme to detoxify it. Initial symptoms include vomiting, salivation, and discoloration of the tongue and gums. Unlike an overdose in humans, liver damage is rarely the cause of death; instead, methemoglobin formation and the production of Heinz bodies in red blood cells inhibit oxygen transport by the blood, causing asphyxiation (methemoglobinemia and hemolytic anemia).…
