Products of the thermal and photosensitised autoxidation of N-alkyl- and NN-dialkyl-amides have been identified. N-n-Alkylamides yield principally N-acylamides, primary amides, and N-formylamides, as a result of initial abstraction of a hydrogen atom from the carbon adjacent to nitrogen. Formation of N-formylamides, and of N-acylamides from N-s-alkylamides, involves C(1)–C(2) bond scission in an N-alkyl

Observations concerning the synthesis of substituted tryptaminederivatives starting from indoles and 1,n-amino alcohols via the borrowing hydrogen process are discussed. This catalytic, single-step, and modular approach to tryptamines and homotryptamines allows the synthesis of branched and nonbranched tryptamines as well as tryptamine-based natural products such as psilocin, bufotenin, and serotonin

The disclosure generally provides methods for preparing compositions comprising alkanolamine alkylamides and polyols. This disclosure further relates to methods for preparing compositions comprising alkanolamine alkylamides and polyols that can be used in formulations that provide moisturization.
based on the search for active compounds with multitarget profiles beneficial in terms of potential side effects and on the implementation of screening for potential multidirectional central activity. Methods Compounds were synthesized by means of chemical synthesis. After antiseizure and neurotoxicity screening in vivo, KM-408 and its enantiomers were chosen for analgesic activity evaluations.

背景 癫痫经常与神经性疼痛并存。我们的方法基于寻找具有多靶点特征的活性化合物,这些特征在潜在副作用方面是有益的,并且基于对潜在多向中枢活性的筛选实施。 方法 化合物是通过化学合成的方式合成的。在体内进行抗癫痫和神经毒性筛选后,选择KM-408及其对映体进行镇痛活性评价。进一步的安全性研究包括小鼠急性毒性、对大鼠正常心电图和血压的影响、大鼠全身体积描记术以及体外和生化测定。已经在大鼠中研究了静脉内和口服给药后的药代动力学。已在大鼠血清和尿液中研究了体内代谢。作为作用机制研究的一部分,进行了放射性配体结合研究。 结果 KM-408 的选定结果: K i sigma = 7.2*10 –8;K i 5-HT 1A = 8.0*10 –7 ; ED 50 MES(小鼠,ip)= 13.3 mg/kg;福尔马林试验(I 期,小鼠,ip)——在 30 mg/kg 时有活性;SNL(大鼠,ip)——在
