Harmse, Rozanne published the artcileActivities of 11-Azaartemisinin and N-Sulfonyl Derivatives against Asexual and Transmissible Malaria Parasites, Related Products of chlorides-buliding-blocks, the publication is ChemMedChem (2017), 12(24), 2086-2093, database is CAplus and MEDLINE.

Dihydroartemisinin (DHA), either used in its own right or as the active drug generated in vivo from the other artemisinins in current clin. use-artemether and artesunate-induces quiescence in ring-stage parasites of Plasmodium falciparum (Pf). This induction of quiescence is linked to artemisinin resistance. Thus, we have turned to structurally disparate artemisinins that are incapable of providing DHA on metabolism Accordingly, 11-azaartemisinin 5 and selected N-sulfonyl derivatives were screened against intraerythrocytic asexual stages of drug-sensitive Pf NF54 and drug-resistant K1 and W2 parasites. Most displayed appreciable activities against all three strains, with IC₅₀ values <10.5 nM. The p-trifluoromethylbenzenesulfonyl-11-azaartemisinin derivative 11 [(4′-trifluoromethyl)benzenesulfonylazaartemisinin] was the most active, with IC₅₀ values between 2 and 3 nM. The compounds were screened against Pf NF54 early and transmissible late intraerythrocytic-stage gametocytes using luciferase and parasite lactate dehydrogenase (pLDH) assays. The 2′-thienylsulfonyl derivative 16 (2′-thiophenesulfonylazaartemisinin) was notably active against late-stage (IV-V) gametocytes with an IC₅₀ value of 8.7 nm. All compounds were relatively nontoxic to human fetal lung WI-38 fibroblasts, showing selectivity indexes of >2000 toward asexual parasites. Overall, the readily accessible 11-azaartemisinin 5 and the sulfonyl derivatives 11 and 16 represent potential candidates for further development, in particular for transmission blocking of artemisinin-resistant parasites.

Rubin, Heather published the artcileScalable Synthesis of N-Acylaziridines from N-Tosylaziridines, Name: Sodium chloro(tosyl)amide trihydrate, the publication is Journal of Organic Chemistry (2013), 78(17), 8865-8871, database is CAplus and MEDLINE.

N-Acylaziridines are important starting materials for the synthesis of chiral amine derivatives The traditional methods for producing these activated aziridines have significant drawbacks. The gram scale synthesis of N-acylaziridines by deprotection of N-tosylaziridines and reprotection with N-hydroxysuccinimide derivatives is described. Mono- and disubstituted aziridines perform well, with complete retention of stereochem. purity. The consistently moderate yields are linked to the N-tosylaziridine deprotection step, while acylation with N-hydroxysuccinimide derivatives is highly efficient.

McManus, E. C. published the artcileUse of coccidia to study the structure-activity relations of a series of p-aminobenzoic acid antagonists, Computed Properties of 5204-46-6, the publication is Develop. Ind. Microbiol. (1965), 44-7, database is CAplus.

Young coccidiosis-susceptible chicks were fed a standard laboratory ration with graded concentrations of test chemicals added just prior to use. On the 2nd day of the test, the chicks were inoculated orally with 100,000 sporulated oocysts of Eimeria maxima; 6 days later birds were killed and weighed, the small intestine homogenized with water, and the oocysts counted. The min. effective diet concentrations of 28 derivatives of p-aminobenzoic acid (I) were determined together with the percent reduction of oocyst count. Remarkably potent anticoccidial compounds were found in a series of ortho-substituted derivatives of I. Groups with high coccidiostatic activity conferring effects were lower alkoxy, alkylthio, and alkyl amino with approx. similar size and shape. The most active compounds, capable of reducing the oocyst count below 25% were the ο-ethoxy derivative, its esters, and N-acyl derivatives, and the ο-chloro, ο-methoxy, ο-isopropoxy, ο-ethyl, and ο-thioethyl derivatives of I. Me 4-acetamido-2-ethoxybenzoate (ethopabate) (II) reduced the oocyst count to nil. The methyl, chloro, nitro, and methoxy derivatives conferred anticoccidial activity when substituted in the ortho position, but not in meta position. Disubstituted derivatives were inactive. The in vivo anticoccidial activity of II and sulfaquinoxaline (III) was overcome completely by simultaneous administration of I. Both II and III potentiated the anticoccidial activity of pyrimethamine. Cross resistance occurred between II and III for many strains of coccidia. The dose-response curves of II and III were parallel, and their anticoccidial activities were additive. II was about 150-fold more potent than III for control of certain strains of E. maxima and Ε. brunetti, and less potent for Ε. tenella. Both II and III were assumed to inhibit biosynthesis of folic acid-type compounds at different steps in the sequence of reactions for synthesis of tetrahydrofolic acid.

The rate of aminolysis of p-nitrophenyl hexanoate by benzylamine in 95.3 mol % dioxane-water was compared to the rate of this reaction when the n-pentyl group in the ester was replaced by a Me₃N⁺(CH₂)₃ group, and the benzyl group in the amine by a ^–O₃SCH₂CH₂ group. The second-order rate constant of the first reaction was 4.21 × 10^-3 L mol^-1 s^-1, the first-order rate constant for the reacting ion pair was 1.88 × 10^-2 s^-1, yielding an effective molarity of 4.47 mol L^-1 as the measure of the rate acceleration caused by this preassembly of the reactants by electrostatic attraction. Further evidence for the intermediacy of an ion pair in the reaction between the oppositely charged reactants was the observation of a special salt effect, the addition of an inert salt causing a decrease in the aminolysis rate.

Heo, Seunga published the artcileBoosting photoredox catalysis using two-dimensional electride as persistent electron donor, Formula: C8H6ClF3, the publication is ACS Applied Materials & Interfaces (2021), 13(36), 42880-42888, database is CAplus and MEDLINE.

Electrides, which have excess anionic electrons, are solid-state sources of solvated electrons that can be used as powerful reducing agents for organic syntheses. However, the abrupt decomposition of electrides in organic solvents makes controlling the transfer inefficient, thereby limiting the utilization of their superior electron-donating ability. Here, we demonstrate the efficient reductive transformation strategy which combines the stable two-dimensional [Gd₂C]²⁺·2e^– electride electron donor and cyclometalated Pt(II) complex photocatalysts. Strongly localized anionic electrons at the interlayer space in the [Gd₂C]²⁺·2e^– electride are released via moderate alcoholysis in 2,2,2-trifluoroethanol, enabling persistent electron donation. The Pt(II) complexes are adsorbed onto the surface of the [Gd₂C]²⁺·2e^– electride and rapidly capture the released electrons at a rate of 10⁷ s^-1 upon photoexcitation. The one-electron-reduced Pt complex is electrochem. stable enough to deliver the electron to substrates in the bulk, which completes the photoredox cycle. The key benefit of this system is the suppression of undesirable charge recombination because back electron transfer is prohibited due to the irreversible disruption of the electride after the electron transfer. These desirable properties collectively serve as the photoredox catalysis principle for the reductive generation of the benzyl radical from benzyl halide, which is the key intermediate for dehalogenated or homocoupled products.

cf. CA 52, 6165d. Heating 11.5 g. MeSiHCl₂ and 4.3 g. C₂H₄ in an ampul in an autoclave 3 hrs. at 320-40° gave mixed MeEtSiCl₂ and MeBuSiCl₂ in yields of 42-80% and 17-28%, resp. The use of a bare steel autoclave tended to lower the yield of MeEtSiCl₂ and raise that of BuMeSiCl₂. Similarly, Ph₃SiH and C₂H₄ in hexane 12 hrs. at 300° gave Ph₃SiEt, m. 68-70°, and Ph₃SiBu, m. 81-2°, along with some (Ph₃Si)₂O, m. 224°. Reaction of MeSiHCl₂ and propylene in the presence of a catalytic amount of H₂PtCl₆ in iso-PrOH in 1 hr. at room temperature gave MePrSiCl₂, which with MeMgBr gave known Me₃SiPr. In the telomerization of MeSiHCl₂ with C₂H₄ at 300°, the increased proportion of the olefin tended to lower steadily the yield of MeSiCl₂Et and MeSiCl₂(CH₂CH₂)₂H, while the yield of MeSiCl₂(CH₂CH₂)₃H remained substantially constant and that of MeSiCl₂(CH₂CH₂)₃H rose rapidly. Elevation of the temperature from 285° to 350° increased the yield of MeSiCl₂Et and decreased that of telomers with n over 3, while the intermediate telomer yield remained substantially constant
