PROCESS FOR THE SYNTHESIS OF COMPOUNDS WHICH ABSORB ULTRAVIOLET RADIATION IN FLOW CONDITIONS AND FORMULATIONS COMPRISING SAME
-
Paragraph 0072, (2021/09/04)
The present invention generally relates to a chemical process under flow conditions for manufacturing compounds which absorb ultraviolet (UV) radiation and protect biological materials as well as non-biological materials from damaging exposure to UV radiation. The present invention further includes formulations and compositions comprising such compounds for use in absorbing UV radiation, as well as methods for protecting biological materials as well as non-biological materials from damaging exposure to UV radiation.

Page/Page column 47-48, (2014/01/08)
The present invention relates to compounds having the general Formula I: which absorb UV radiations and protect biological materials as well as non-biological materials from damaging exposure to UV radiations. The present invention also relates to formulations and compositions comprising such compounds for use in absorbing UV radiations and in protecting biological materials as well as non-biological materials against UV radiations.
Synthesis of new acridines and hydrazones derived from cyclic β-diketone for cytotoxic and antiviral evaluation
El-Sabbagh, Osama I.,Rady, Hanaa M.
experimental part, p. 3680 - 3686 (2009/12/04)
Cyclic β-diketone namely, dimedone was utilized to prepare different chemical entities whether cyclic such as acridines, thiadiazole and triazole or acyclic systems as hydrazide, hydrazones, thiosemicarbazide and semicarbazide. The structures of the novel compounds were determined using elemental ana-lyses and various spectroscopic methods. Most acyclic derivatives especially semicarbazide 19, hydrazide 9 and thiosemicarbazide 16 showed a higher in vitro cytotoxic activity against hepatoma cell line (HepG2) than the cyclized acridine derivatives. The antiviral activity of the new compounds against Hepatitis A Virus (HAV) using the plague infectivity reduction assay revealed that the acridine 4 and the hydrazone 12 were more active than the reference drug amantadine.

Secondary 2-cyano- and 2-ethoxycarbonylaziridines react with acetylenic compounds and activated vinylic chlorides to gives 2-cyano and 2-ethoxycarbonyl N-vinylaziridines.The nucleophile-catalysed isomerization of these compounds generally gives α,β-dehydr
Reactions between Enaminones and Enones. Part 2. C versus N-Alkylation with Cyclohex-2-enone. Structure Confirmation by Reduction of a Dienaminone Derivative of Dehydrated Dimedone Dimer
Chaaban, Ibrahim,Greenhill, John V.,Ramli, Mohamed
, p. 3120 - 3124 (2007/10/02)
Primary and secondary enaminones derived from cyclohexane-1,3-dione, dimedone, and acetylacetone react with cyclohexenone to give exclusively C-alkylated derivatives.In every case the products form carbinolamines which exist as 1-hydroxy-2-azacyclo
