The invention includes methods of processing an initial di-carbonyl compound by conversion to a cyclic compound. The cyclic compound is reacted with an alkyating agent to form a derivative having an alkylated ring nitrogen. The invention encompasses a method of producing an N-alkyl product. Amonia content of a solution is adjusted to produce a ratio of ammonia to di-carboxylate compound of from about 1:1 to about 1.5:1. An alkylating agent is added and the initial compound is alkylated and cyclized. The invention includes methods of making N-methyl pyrrolidinone (NMP). Aqueous ammonia and succinate is introduced into a vessel and ammonia is adjusted to provide a ratio of ammonia to succinate of less than 2:1. A methylating agent is reacted with succinate at a temperature of from greater than 100 °C to about 400 °C to produce N-methyl succinimide which is purified and hydrogenated to form NMP.
Upregulation of the transcription factor Nrf2 by inhibition of the interaction with its negative regulator Keap1 constitutes an opportunity for the treatment of disease caused by oxidative stress. We report a structurally unique series of nanomolar Keap1inhibitors obtained from a natural product-derived macrocyclic lead. Initial exploration of the structure-activity relationship of the lead, followed

principal reaction product. In the absence of esterase, the order of DNA alkylation for all of the acyltriazenes did not correlate with their respective rates of decomposition, leading to the conclusion that the triazenes did not decompose by the expected mode of uncatalyzed N(2)-N(3) heterolyic cleavage. The major DNA alkylation product from the N(3)-methyltriazenes was 7-methylguanine, instead of the expected
The present invention relates to novel dithiinetetra(thio)carboximides, to processes for preparing these compounds, to compositions comprising these compounds, and to the use thereof as biologically active compounds, especially for control of harmful microorganisms in crop protection and in the protection of materials and as plant growth regulators.

The invention relates to novel benzimidazole and imidazopyridine derivatives having general formula (I), which have a good affinity with certain sub-types of melanocortin receptors, particularly MC4 receptors. Said derivatives are particularly suitable for the treatment of pathological states and diseases involving one or more melanocortin receptors. The invention also relates to pharmaceutical compositions containing said products.
