Abstract:
Five N-(4-cyclopentylphenyl)haloalkanecarboxamides were reacted with 1-methylpiperazine and 1-(2-hydroxyethyl)piperazine to give the corresponding N-(4-cyclopentylphenyl)piperazinoalkanecarboxamides Iab -Vab. Their reduction with lithium aluminium hydride afforded the triamines VIIab - XIab. Acylation of the N-(4-methylpiperazino)alkyl-4-cyclopentylanilines Xa and XIa with propionyl chloride resulted in the propionanilides XIVa and XVa, whereas a similar reaction of the N-(4-(2-hydroxyethyl)piperazino)alkyl-4-cyclopentylanilines VIIb and IXb - XIb produced the propionoxypropionanilides XIIc -

Abstract:
Several compounds derived from nicotinic acid were prepared within a more extensive programme aiming at the synthesis of new substances with expected antihistamine and antidepressant activity. Some of these compounds display certain structural resemblance with the antidepressant agent piberaline (EGYT 475, Trelibet®, I) and its analogues. The products were used as intermediates for the synthesis of further compounds and most of them were subjected to pharmacological testing. Substituted nicotinic acid piperazides IIa - IId and IVa - IVe were obtained by reactions of nicotinoyl chloride (prepar

Multiple validation techniques like CatScramble, test set prediction, and mapping analysis of advanced known antagonists have been employed to check the predictive power and robustness of the developed model.

Recent advances in process design for solvent-based, post-combustion capture (PCC) processes, such as the Piperazine/Advanced Flash Stripper (PZ/AFS) process, have led to a reduction in the energy required for capture. Even though PCC processes are progressively improving in Technology Readiness Levels (TRL), with a few commercial installations, incorporating carbon capture adds cost to any operation. Hence, cost reduction will be instrumental for proliferation. The aim of this work is to improve process economics through optimization and to identify the parameters in our economic model that h
