The Relation Between Gorenstein Derived and Pure Derived Categories
Bulletin of the Iranian Mathematical Society, 2022The authors study the relation between Gorenstein derived and pure derived categories under some conditions, and also study the relation between Gorenstein singularity and pure singularity categories. Moreover, they describe the bounded Gorenstein derived category by pure projective modules, under a fairly strong assumption on the ring.

, 2011 Amphetamine derivative related deaths
Forensic Science International, 1997Amphetamine its methylendioxy (methylendioxyamphetamine methylenedioxymethylamphetamine, methylenedioxyethylamphetamine) and methoxy derivatives (p-methoxyamphetamine and p-methoxymethylamphetamine) are widely abused in Spanish society. We present here the results of a systematic study of all cases of deaths brought to the attention of the Madrid ...

Strongly Regular Relations Derived from Fundamental Relation
Journal of Algebraic Hyperstructures and Logical Algebras, 2023We introduce a new regular relation δ on a given group G and show that δ is a congurence relation on G, with respect to module the commutator subgroup of G. Then we show that the effect of this relation on the fundamental relation β is equal to the fundamental relation γ, and we conclude that, if ρ is an arbitrary strongly regular relation on the ...

Selenotyrosine and related phenylalanine derivatives
Bioorganic & Medicinal Chemistry, 2001A new series of Se-substituted phenylalanine derivatives has been synthesized having the para position of the phenyl ring substituted by selenocyanate (-SeCN), seleninic acid (-SeO(2)H), or selenol (-SeH) functional groups. The starting material for synthesis was 4'-aminophenylalanine, which is readily available in DL- or L- forms.

Silipramine and related derivatives
Journal of Organometallic Chemistry, 1978A series of new 10,11-dihydro-5H-dibenzo[b,f]silepins are prepared from the reaction o,o′-dilithiobibenzyl with the chlorosilanes HSiCl3, ClCH2CH2CH2SiCl3, MeSiHCl2 and MeSi(CH2CH2CH2Br)Cl2. The only isolated silepin product produced from HSiCl3 is the spiro derivative.

Peptide derivatives of tylosin-related macrolides
Russian Journal of Bioorganic Chemistry, 2007Approaches to the synthesis of model compounds based on the tylosin-related macrolides desmycosin and O-mycaminosyltylonolide were developed using specially designed peptide derivatives of macrolide antibiotics to study the conformation and topography of the nascent peptide chain in the ribosome tunnel.

Indole Derivatives Related to Lysergic Acid*,†
Journal of the American Pharmaceutical Association (Scientific ed.), 1951Abstract Several new compounds related ro lysergic acid have been prepared and characterized. Four of these compounds are indole derivatives which have been prepared in quantities sdicient for pharmacological testing. Methods for the successful synthesis of the following are described: ethyl ester of 1-(3-indolylmethyl)guvacine.
