Malaria, despite many efforts, remains among the most problematic infectious diseases worldwide, mainly due to the development of drug resistance by Plasmodium falciparum. The antibiotic fosmidomycin (FSM) is also known for its antimalarial activity by targeting the non-mevalonate isoprenoid synthesis pathway, which is essential for the malaria parasites but is absent in mammalians. In this study, we synthesized and evaluated against the chloroquine-resistant P. falciparum FcB1/Colombia strain, a series of FSM analogs, derivatives, and conjugates with other antimalarial agents, such as artemisinin (ART) and aminochloroquinoline (ACQ). The biological evaluation revealed four new compounds with higher antimalarial activity than FSM: two FSM-ACQ derivatives and two FSM-ART conjugates, with 3.5-5.4 and 41.5-23.1 times more potent activities than FSM, respectively.

Perylenediimides (PDIs) have emerged as potential materials for optoelectronic applications. In the current work, four PDI derivatives, substituted at imide nitrogen with 2,6-diisopropyl phenyl, 2-nitrophenyl, diphenylmethylene, and pentafluorophenyl groups, have been synthesized from perylene 3,4,9,10-tetracarboxylic dianhydride using a facile imidization synthesis process. PDI derivatives have been spectroscopically characterized for their structure and optical properties. Temperature-variable absorption and emission spectroscopy study confirmed the H-aggregation property. H-aggregation along with strong emission suggests the slipped pi-pi stacking of PDI molecules. Electrochemical analysis was performed for their redox behavior and calculation of lowest unoccupied molecular orbital and highest occupied molecular orbital energy levels. Scanning electron microscopy showed the formation of ordered structures. The PDI derivatives showed excellent electron conductivity without doping and 5-10x higher electron mobility than that of state-of-the-art fullerene acceptor phenyl-C-61 -butyric acid methyl ester (PC61BM). Finally, the charge generation and charge transfer phenomenon was studied by transient absorption spectroscopy (TAS). TAS showed ultrafast charge transfer from the poly(3-hexyl)thiophene (P3HT) donor polymer to PDI and formation of long-lived charge-separated states similar to fullerene derivative PC61 BM/P3HT blends. Such PDI derivatives with excellent solubility and photophysical and electronic properties are potential n-type materials to be used in organic electronic devices.

A mild, atom-economic, and metal-free alpha-C-H amination of ethers using relatively stable nonafluorobutanesulfonyl (nonaflyl, Nf) azide as the aminating reagent to give N-sulfonyl hemiaminals is reported. This enables unprecedented C(sp(3)) difunctionalization reactions, leading to diverse functionalized amino group containing compounds starting from simple ethers in one pot.

N,N’-Acetals are sensitive compounds, and the challenging asymmetric synthesis of acyclic N,N’-acetals by the general addition of amines to ketimines has never been reported so far. In this study, highly enantioselective addition of aryl amines to isatin-derived ketimines catalyzed by chiral urea derived from quinine was developed. A series of new acyclic N,N’-acetals were constructed by this protocol in high to excellent yields (78-99%) and high to excellent enantioselectivities (76-96% ee).

We report on a switchable rotaxane molecular shuttle that features a pseudo-meso 2,5-disubstituted pyrrolidine catalytic unit on the axle whose local symmetry is broken according to the position of a threaded benzylic amide macrocycle. The macrocycle can be selectively switched (with light in one direction; with catalytic acid in the other) with high fidelity between binding sites located to either side of the pyrrolidine unit. The position of the macrocycle dictates the facial bias of the rotaxane-catalyzed conjugate addition of aldehydes to vinyl sulfones. The pseudo-meso non-interlocked thread does not afford significant selectivity as a catalyst (2-14 % ee), whereas the rotaxane affords selectivities of up to 40 % ee with switching of the position of the macrocycle changing the handedness of the product formed (up to 60 % Delta ee).

A small group of lipid-conjugated Smac mimetics was synthesized to probe the influence of the position of lipidation on overall anti-cancer activity. Specifically, new compounds were modified with lipid(s) in position 3 and C-terminus. Previously described position 2 lipidated analog M11 was also synthesized. The resulting mini library of Smacs lipidated in positions 2, 3 and C-terminus was screened extensively in vitro against a total number of 50 diverse cancer cell lines revealing that both the position of lipidation as well as the type of lipid, influence their anti-cancer activity and cancer type specificity. Moreover, when used in combination therapy with inhibitor of menin-MLL1 protein interactions, position 2 modified analog SM2 showed strong synergistic anti-cancer properties. The most promising lipid-conjugated analogs SM2 and SM6, showed favorable pharmacokinetics and in vivo activity while administered subcutaneously in the preclinical mouse model. Collectively, our findings suggest that lipid modification of Smacs may be a viable approach in the development of anti-cancer therapeutic leads.

A series of phosphonic acid and bisphosphoramidate derivatives were synthesized and characterized. The bioactivities against the fungal pathogen Macrophomina phaseolina and human acetylcholinesterase AChE enzyme were studied using QSAR based on multiple linear regression. L17, with (p-Cl-C6H4-NH) (p-Cl-C6H4)C(H)P(O)(OC2H5)(2) skeleton, demonstrated a great mortality on the M. phaseolina mycelial growth by 83% inhibition at 150 mg/L; the other tested derivative showed moderate to weak antifungal activity against the fungus. QSAR model based on the GA-MLR method revealed the importance of 3D descriptors (De, Mor18e, H8m, and Mor30p) on the antifungal activity. It showed good capability in predicting the fungicidal activity of the studied molecules. Another derivative, L5, with (m-CH3-NC5H4-NH)(m-CH3-C6H4)C(H)P(O)(OCH3)(2) skeleton displays the most potent anti-AChE activity. The electronic parameters, Delta EL-H, and E-LUMO, have the highest contribution of human AChE. The authors suggest that these models could be usefully employed in designing more effective crop protection compounds without side effects on non-target organisms.

Three novel hexacoordinated nickel catalysts containing salicylaldbenzhydrylimine ligand and tetrahydrofuran heterocycle, Ni{(THF) (3-R-1) (5-R-2)C6H2(O)CHNCH(C6H5)(2)}(2), (R-1 = Br, R-2 = H, Ni1; R-1 = Br, R-2 = Br, Ni2; R-1 = Cl, R-2 = Cl, Ni3.), were synthesized and their molecular structures were confirmed by X-ray crystallography. Ni1-Ni3 catalysts exhibited high activities (0.53-2.11 x 10(6) g(polymer)/mol(Ni).h) toward norbornene homopolymerization and high activity (0.29-2.62 x 10(5) g(polymer)/mol(Ni).h) to copolymerization of norbornene and 1-hexene. When the 1-hexene feed ratio was changed from 10 to 70%, the 1-hexene content in the obtained copolymers could be controlled to 8.23-26.58%. The Ni3 with R-1 and R-2 were both electron withdrawing groups (-Cl) on the aromatic ring of salicylaldehyde, showed the highest activity as well as the highest 1-hexene insert ratios. At the same time, only a small amount of B(C6F5)(3) cocatalyst (5 x 10(-5) mol) need to be consumed in the copolymerization process. In addition, the obtained copolymers had a high thermal decomposition temperature (T-d > 386 degrees C) and a low glass transition temperature (T-g = 208.67-237.42 degrees C), which showed that the processability of these polymers was improved while the high thermal decomposition temperature was kept. The copolymers also exhibited good solubility in general organic solvents and high optical transparency in the visible region. (C) 2020 Elsevier B.V. All rights reserved.

A broad-spectrum, catalytic method has been developed for the synthesis of sulfonamides and sulfamates. With the activation by the combination of a catalytic amount of 1-hydroxybenzotriazole (HOBt) and silicon additives, amidations of sulfonyl fluorides and fluorosulfates proceeded smoothly and excellent yields were generally obtained (87-99 %). Noticeably, this protocol is particularly efficient for sterically hindered substrates. Catalyst loading is generally low and only 0.02 mol % of catalyst is required for the multidecagram-scale synthesis of an amantadine derivative. In addition, the potential of this method in medicinal chemistry has been demonstrated by the synthesis of the marketed drug Fedratinib via a key intermediate sulfonyl fluoride 13. Since a large number of amines are commercially available, this route provides a facile entry to access Fedratinib analogues for biological screening.
