    T. Heinze et. al. reported the synthesis of new 6-deoxy-6-pheylethylamino cellulose derivatives with DSamino 0.4-0.6 by nucleophilic displacement of cellulose tosylates (DSTos 0.74 and 1.29) with a racemic mixture of 1-phenylethylamine under homogeneous conditions, in DMF/H2O82, scheme 30. The optical properties of these deoxyamino cellulose derivatives was studied. A regioselective synthesis of 6-amino-6-deoxycellulose, 6-N-sulfonated, and 6-N-carboxymethylated deoxycellulose were described by C. Liu et.…

    The optimized PF0 encapsulated hybrid NCs formulation was achieved by a two-step process (Fig 1) using nanoprecipitation and subsequently coating with chitosan. In Step-I, the nanoprecipitation technique was used to prepare PF0 loaded BSA NCs (PF0-ANC). In this nanoprecipitation technique, acetone was used as a desolvent [40]. Varying concentrations of PF0 solutions (125µM - 375µM) and BSA solution (156.25µM – 468.75µM) (Table 1) were mixed in a glass vial. The PF0 BSA solution was then added slowly, at a controlled speed of 0.2 ml/min using syringe pump, under continuous stirring at 600 rpm and the stirring was continued overnight to allow acetone evaporation.…

    Many 2,3 disubstituted quinazolinone derivatives have good antimicrobial and antifungal activities [19,20]. On the other hand substitution at 3rd position of bromo quinazolinone derivatives with phenyl ring show potential antimicrobial and antifungal activities [21,22]. Chacones, pyrazole, isoxazole and thiopyrimidine have antibacterial and antifungal activities [23-26]. Continuation of our research program which aim to synthesis of new biologically active quinazolin-4-one derivatives [4-8, 22], we synthesized new bromo quinazolinone derivatives substituted at 3rd position with chalcones,pyrazole, isoxazole or thio pyrimidine moiety bearing para chloro phenyl moiety at position 2. 2.…

    4.12 – Development and optimization of p-aminoquinoline derivatives [Adapted from [47b]] Ferroquine (72) is the first organometallic drug which has a ferrocenyl group covalently linked to a chloroquine by its tertiary amine side chain. This drug overcomes the resistance problem of P. falciparum and has high potency for P. vivax, by targeting of lipids, inhibition the formation of hemozoin and generation of reactive oxygen species. [58] Amodiaquine (62) is another potent quinoline derivative. Its p-hydroxyanilino moiety suffers enzymatic oxidation to quinone imine, a reactive metabolite. To overcome this problem, O’Neill group developed a series of isomers by interchange the hydroxyl group and the mannich side chain, which originated the GSK369796 (81) that entered in phase I of clinical trials.…

    A novel solid-phase synthesis methodology of N-substituted-2-aminothiazolo[4,5-b]pyrazine derivatives was developed. The key step in this synthesis strategy is tandem reaction of isothiocyanate terminated resin 2 with o-halo-2-aminopyrazine, affording cyclized 2-aminothiazolo[4,5-b]pyrazine resin 4. To increase the diversity of our library, Suzuki coupling reaction was performed at the position C6. Further functionalization of 2-aminothiazolo[4,5-b]pyrazine core skeleton with various electrophiles such as alkyl halides, acyl chlorides, and sulfonyl chlorides and cleavage from the resin with TFA in DCM generated N-alkyl-, N-acyl-, and N-sulfonyl-2-aminothiazolo[4,5-b]pyrazine derivatives. This synthetic strategy can efficiently provide a library…
