1. The production of a new lysergic acid derivative, identified as D-lysergic acid α -hydroxyethylamide, in submerged culture and in yields up to 1 mg/ml. and above, by a strain of Claviceps paspali Stevens & Hall is reported; this substance can be converted in high yields into D-lysergic acid amide. 2. The morphological properties of this strain under different culture conditions are examined and it is shown that it grows in a form resembling natural sclerotia. 3. The biochemical culture conditions for the production of the new lysergic acid derivative in shake flasks and in stirred fermenters, the course of the fermentation, the methods for the isolation and purification of the substance and its transformation products and some of its chemical and physical properties are described.

Using a strain of Claviceps paspali Mar 488 it has been shown that alanine-2-C14 is incorporated with high efficiency in the carbinol amide moiety of D-Lysergic acid-α-hydroxyethylamide=II. After feeding of ᴅʟ-alanine-15N, DL-aspartic acid-15N and ʟ-glutamine-CO-15NH2 the highest specific incorporation rate was observed with DL-alanine-15N. Short term experiments with ᴅ,ʟ-alanine-15N revealed, that the greater part of the 15N-excess is localized in the N-atom of the side-chain of II. The carbinolamide moiety of the isolated alkaloid arises probably from alanine or a closely related compound.

Chemical changes in the mycelium of the conidial Claviceps paspali mutant strain, isolated after γ irradiation, were followed during the course of submerged fermentation and compared with the mycelial parent strain; both strains are capable of producing simple lysergic acid derivatives. The syntheses of lipids, carbohydrates, phosphates, nucleic acids, proteins, and alkaloids, as well as nutrient uptake, were determined. It was found that conidiation induced by mutagenic treatment was accompanied by a set of changes in the metabolic pattern. In the conidial mutant, the primary and secondary metabolic activities were repressed and the protein to nonprotein compound ratio of the cells was changed in favour of protein compounds.

<b><i>Background:</i></b> In this article, we present an evaluation of online psychoactive substance trade via Telegram, a free encrypted social media messenger service. The evaluation took place during the COVID-19 pandemic, which allowed us to monitor the effects of the spring 2020 lockdown in the Netherlands on substance trade via Telegram. <b><i>Objective:</i></b> The objective of this study was to evaluate whether changes in psychoactive substance trade on Telegram markets in the Netherlands can be observed during the COVID-19 pandemic. <b><i>Results:</i></b> Between December 2, 2019, and June 29, 2020, a total of 70,226 posts appeared in two analyzed Telegram groups. A total of 5,643 posts were psychoactive substance related. Based on the analyzed posts, Telegram is mostly a ‘“sellers” market as only a minority of the posts (6.3%) could be identified as a request for a substance. The proportion of posts related to specific substances varied between the periods before, during, and after the lockdown. The proportion of posts on the stimulants ecstasy, cocaine, and amphetamine was lower during the lockdown than before and after. For psychedelics – ketamine, lysergic acid diethylamide (LSD), and 2,5-dimethoxy-4-bromophenethylamine (2C-B) – and other substances, there was a relative increase in the number of posts during the lockdown, which was maintained after the lockdown. <b><i>Conclusions:</i></b> Telegram analysis shows that in the Netherlands, online psychoactive substance trade may have been affected during the COVID-19 pandemic. The direction of this effect was different for different classes of substances.

A localized pulmonary infarction was produced by injecting a starch suspension into the pulmonary artery wedge position of one lung lobe in pentobarbitalized dogs, and the effect of three so-called antiserotonins on the ensuing pulmonary edema was determined. Edema was inhibited in the nonembolized lung lobes in 88% of the B.A.S. (1-benzyl-2-methyl-5-methoxytryptamine HCl), 45% of the DHE (dihydroergotamine), and 12% of the BOL (2-brom- d-lysergic acid diethylamide) dogs. Reasons are given for assuming that the actions of B.A.S. and DHE are due to their antiadrenergic rather than to any antiserotonin properties which they may have. Serotonin, therefore, at most has a slight role in the pulmonary edema formation caused by starch emboli. It is postulated that the emboli by producing an infarct and setting up a reflex mediated through the sympathetic nervous system, cause the release in turn of catecholamines and of histamine, the latter being immediately responsible for the capillary permeability change leading to pulmonary edema.
