Author is Nija, B.; Rasheed, Arun; Kottaimuthu, A..

The current research work investigate the neuronal pathway associated with NSAIDs that lead to the reduction in the initiation and progression of neurodegenerative diseases such as Alzheimer’s disease, Parkinsonism, etc. This research was developed amino acid prodrugs of the active enantiomer of ibuprofen, (+)-IBN and checks the pharmacol. effects, neuroprotective effect, anti inflammatory effect and anti-ulcerogenic effect. The treatment using (+)-IBN reduced the action of micoglia and the release of cytokine especially TNFα that are mainly involved in the neurodegenerative process. (+)- IBN reduced the deposition of soluble beta amyloid plaque by inhibiting the amyloid precursor protein, beta-secretase 1 and also enhancing the degradation process of beta amyloid via induction of insulin degrading enzyme. (+)-IBN also showed the property that the reduction in the TAU misfolding process. Therefore, the synthesized (+)-IBN amino acid prodrugs treatment effectively produce neuroprotective action, both restoring memory realed risk factors and reversing multiple brain neuropathol. hallmarks. The current research study developed the three amino acid prodrugs of (+)-ibuprofen by conjugating with L-Ph alanine, L-tryptophan and L-tyrosine also the physico-chem. characterization and spectral characterization was done. This study modify the carboxylic acid functional group present in the NSAIDs that lead to the formation of prodrugs with enhanced anti-inflammatory activity, reduced side effects and protective effect against neurodegenerative processes.

The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: H-Trp-OMe.HCl( cas:7524-52-9 ) is researched.SDS of cas: 7524-52-9.El Rayes, Samir M.; Ali, Ibrahim A. I.; Fathalla, Walid; Mahmoud, Mostafa A. A. published the article 《Synthesis, molecular docking and biological evaluation of some new benzotriazines》 about this compound( cas:7524-52-9 ) in International Electronic Conference on Synthetic Organic Chemistry, 23rd, Nov. 15-Dec. 15, 2019. Keywords: benzotriazinone hydrazide dipeptide amide preparation antibacterial antitumor docking. Let’s learn more about this compound (cas:7524-52-9).

Me 2-(4-oxobenzotriazin-3(4H)-yl)alkanoates I [X = CH2, CH2CH2, CH(i-Pr); X1 = MeO] proved to be important intermediates for the preparation of some biol. interesting compounds containing the benzotriazinone ring system. The above compounds were prepared by direct diazotization of Me anthranilate followed by addition of amino acid esters hydrochloride in a one-pot strategy. An equivocal synthesis of compound I (X = CH2; X1 = MeO) was achieved by alkylation of benzotriazin-4(3H)-one with Me chloroacetate. A series of N-alkyl-2-(4-oxobenzotriazin-3(4H)-yl) alkanamides I (X = CH2, CH2CH2; X1 = NR1R2; R1 = i-Pr, n-Bu, t-Bu, cyclohexyl, etc., R2 = H; R1R2N = 1-piperidinyl, 4-morpholinyl) and Me 2-(2-(4-oxobenzotriazin-3(4H)-yl)alkanamido)alkanoates (dipeptides) I [X = CH2, CH2CH2; X1 = NHR3; R3 = MeO2CCH2, MeO2CCH(i-Bu), MeO2C(CH2)3, MeO2CCH(indol-3-ylmethyl)] were prepared via azide coupling from compounds I (X = CH2, CH2CH2; X1 = MeO). Esters I (X = CH2, CH2CH2; X1 = MeO) were converted into the corresponding hydrazides followed by condensation with aldehydes, such as 4-methoxybenzaldehyde, 4-dimethylaminobenzaldehyde and arabinose, to afford the corresponding hydrazone derivatives. All the synthesized compounds were subjected to the mol. docking using MOE 2008-10 software as agonists for E. coli Fab-H receptor and Vitamin D receptor for antibacterial and anticancer evaluation, resp. The most pronounced strong binding affinity towards the target E. coli Fab-H receptor was shown by the parent benzotriazin-4(3H)-one and compounds I [X = CH2, X1 = i-PrNH; X = CH2CH2, X1 = MeO2CCH2, MeO2C(CH2)3; X = CH2, X1 = 4-MeOC6H4CH:NN, 4-Me2NC6H4CH:NN; X = CH2CH2, X1 = 4-Me2NC6H4CH:NN]. On the other hand, the most pronounced strong binding affinity towards the target Vitamin D receptor were benzotriazin-4(3H)-one and compounds I [X = CH2, X1 = MeO2C(CH2)3; X = CH2CH2, X1 = MeO2CCH(indol-3-ylmethyl); X = CH2, X1 = 4-MeOC6H4CH:NN]. The in-vitro antibacterial activity of highest binding affinity docked compounds were tested against E. coli, Staphylococcus aureus and Salmonella spp. All the tested compounds gave effective pos. results against E. coli with inhibitory zone of about 1.1 cm, while were inactive against Staphylococcus aureus and Salmonella spp. The in-vitro cytotoxic activity of the highest binding affinity docked compounds were tested against human liver carcinoma cell line (HepG2) cancer cell lines. Many compounds showed potent cytotoxic activity with low IC50 values, especially benzotriazin-4(3H)-one (6.525μM) and I (X = CH2; X1 = 4-MeOC6H4CH:NN) (10.97μM) compared to standard drug doxorubicin (5.8μM).

The first enantioselective total synthesis of (-)-aspidophylline A (I), including assignment of its absolute configuration has been accomplished. A key element of the synthesis is a highly enantioselective indole allylic alkylation/iminium cyclization cascade which was developed by employing a combination of Lewis acid activation and an iridium/ligand catalyst. This strategy relies on the direct use of 2,3-disubstituted indoles with secondary allylic alcs. appended at C2 and heteronucleophiles appended at C3, indoles which are easily prepared from simple starting materials under C-H activation conditions.
