Atkamine is a complex marine pyrroloiminoquinone alkaloid that comprises a heptacyclic scaffold bearing five different heterocycles and four contiguous stereocenters, and therefore it is a highly challenging target for synthetic chemists. We herein reported a modular synthetic strategy toward this alkaloid, featuring a formal [5 + 2] annulation and an asymmetric Michael addition. The efficient synthesis of the long-chain aliphatic aldehyde and chiral amino acetal fragments have been achieved. A simplified tetracyclic intermediate bearing the core structure of atkamine has been successfully constructed through the formal [5 + 2] annulation.

A series of novel thiouracil derivatives 9 containing an oxadiazole moiety have been synthesized by structural modification of a lead SecA inhibitor, 2. These compounds have been evaluated for their antibacterial activities against Bacillus amyloliquefaciens, Staphylococcus aureus and Bacillus subtilis. Among them, compounds 9g and 9n exhibited promising antibacterial activities against the tested strains. Compound 9g was also tested for its inhibitory activities against SecA ATPase, and the IC50 value of compound 9g was 19.9 mu g/mL, lower than that of compound 2 (20.8 mu g/mL). Molecular docking work indicates that compound 9g likely occupies the pocket formed by SecA IRA2 and NBD domain.

A series of Ephedra based oxadiazinones have been prepared, acylated, and examined in the asymmetric conjugate addition reaction with Grignard reagents in the presence of copper(I) bromide-dimethyl sulfide complex. The highest diastereoselectivity that was obtained in the conjugate addition reaction was observed with the (1R,2S)-ephedrine based N-4-methyloxadiazinone (5:1 d.r.) favoring the formation of the (S)-configuration of the conjugate addition product. Efforts to enhance the level of diaster-eoselection via increasing the steric volume of the stereo-directing N-4-substituent of the oxadiazinone (N-4- = p-methoxyphenyl or -isopropyl) led to an observed decrease in the level of diastereoselection. A computational study was conducted to examine the conformations adopted by the N-4-methyloxadiazinone vs. the N-4-isopropyl-oxadiazinone that yielded the lower diastereoselectivity. An argument is made for the stereoelectronic properties of the N-4-substituent being the cause of both the moderate diastereoselectivity and the unexpected facial preference for the conjugate addition.

Fingerprint development is one of the most useful techniques in forensic investigation. The powder method is widely used, as it consists of a non-destructive testing. However, some of the powders commonly used are toxic and dangerous to human health. In this sense, monofunctional analogues of curcumin (3a-e) are proposed as novel coloring powders for the development of latent fingerprints. Granulometric and scanning electron microscopy analysis were performed for a better understanding of the interaction between developers and substrates. The best results for the development of fingerprints were obtained with compound (1E,4E)-1,5-di-p-tolylpenta-1,4-dien-3-one (3b). Development with this compound was specific and allowed detection both from male and female donors. Also, in an in vitro experiment, compound 3b presented low cytotoxicity in a mammalian cell line. Based on that, a novel alternative for latent fingerprint developers was proposed.

Background: One of the principal factors in the field of research in green chemistry is to drive chemical reactions using ultrasonication as a versatile synthetic tool. Moreover, nanostructured metal salts occupy an important position as low cost, efficient, heterogeneous, and green catalysts in chemical reactions. Pyrimidine has also acquired significance because it is a core structure in a variety of natural and non-natural agents, many of which display versatile biological activities and medical applications. Objective: The aim of this study was to explore the role of nickel(II) chromite nanoparticles (NiCr2O4 NPs) as a green and recyclable catalyst for the synthesis of 2,4-diamino-6-arylpyrimidine-5-yl cyanides under ultrasonic radiation. Methods: A direct cyclocondensation reaction of guanidine nitrate, aromatic aldehydes, and malononitrile was performed using NiCr2O4 NPs as an effective heterogeneous catalyst under ultrasonic radiation at room temperature conditions to prepare 2,4-diamino-6-aryl-pyrimidine-5-yl cyanides in high yields. The described catalyst was prepared successfully according to a simple hydrothermal route and fully characterized by the X-Ray diffraction (XRD) technique, dispersive energy X-Ray (EDS) analysis, scanning electron microscopy (SEM), and dynamic light scattering (DLS). Results: A number of 2,4-diamino-6-aryl-pyrimidine- 5-yl cyanides were effectively synthesized in high yields (94-98%) within short reaction times (15 min). All synthesized compounds were well characterized by IR, 1H and 13C NMR spectroscopy, and also by elemental analyses. Conclusion: In conclusion, a simple, efficient, and green synthesis of 2,4-diamino-6-arylpyrimidine-5-yl cyanides was developed using NiCr2O4 NPs as a green nanocatalyst, and under ultrasound radiation as a green tool. The mild reaction conditions, avoiding the use of toxic solvents or reagents, high atom economy, high yields, and simple workup are the attractive features of this new protocol.

(E)-N’-4-methoxybenzylidene-5-methyl-1H-pyrazole-3-carbohydrazide (E-MBPC) has been synthesized and characterized by FT-IR, H-1 & C-13 NMR and ESI-MS spectroscopic methods. The (E)-configuration of hydrazonoic group was confirmed by single-crystal X-ray diffraction. Theoretical structures of E-MBPC in both gas phase and aqueous solution have been optimized by using hybrid B3LYP/6-311++G** calculations. Calculations in solution have shown that dipole moment increases from 7.97 D in the gas phase to 13.68 D in solution with solvation energy of -131.34 kJ/mol. Atomic charges have evidenced that the protonation of E-MBPC in solution could occur only in the N28 atom because those charges on this atom show negative values. Mapped MEP surfaces show that the nucleophilic sites is located on the O21 and N28 atoms including the N16 atom while the electrophilic sites are observed on the N24-H27 and N18-H19 bonds. NBO calculations support the high stability of E-MBPC in solution while frontier orbitals studies suggest low reactivity of E-MBPC in both media, as compared with the (E)-N’-(4-(dimethylamino)benzylidene)-5-methyl-1H-pyrazole-3-carbohydrazide derivative. The vibrational assignments of 93 vibration modes expected for E-MBPC were reported together with the corresponding force fields and force constants in both media. The predicted Raman and Ultraviolet-visible spectra were also reported for E-MBPC at the same level of theory. Good correlations were obtained between the predicted H-1- and C-13 NMR spectra and the corresponding experimental ones. In addition, molecular docking studies between the title ligand and 4AMJ protein were performed. Docking results revealed that the title compound can be designed as a potential anti-diabetic agent.

Fennel (Foeniculum vulgare Miller) is a popular aromatic plant native to the Mediterranean basin and cultivated worldwide that is valued for the nutritional and health benefits of its fruits. Headspace solid-phase microextraction of 12 fennel accessions of cultivated (F. vulgare subsp. vulgare) and wild forms (F. vulgare subsp. piperitum) of different origins was carried out for assessing their volatile distribution. Fifty-four volatiles were identified, with ethers amounting for the major class at ca. 52-99% attributed to the abundance of (E)-anethole and estragole. Several subsp. vulgare accessions proved to be excellent sources of the chief aroma (E)-anethole (95.9-98.4%), whereas high levels of estragole at ca. 72% were observed in subsp. piperitum from Minia and Khartoum and must be considered in the safety assessment of fennel. Other volatile classes were detected including ketones, esters, aldehydes, alcohols, and hydrocarbons (monoterpenes, sesquiterpenes, and diterpenes). Fenchone exceeded 15% of the total volatiles in some fennel specimens, linked to a conspicuous bitter aftertaste. The members of subsp. piperitum were more enriched in monoterpene hydrocarbons with sabinene found exclusively in these, while subsp. vulgare comprised a higher content of ethers. Principle component analysis determined isoterpinolene as a special component in subsp. piperitum. In all specimens from the same group, estragole was the most distinguished volatile compound according to the findings from orthogonal partial least squares-discriminant analysis. The highest estimated estragole levels were detected in subsp. piperitum from Minia at 89.8 mg/g. This comparative study provides the first comprehensive insight into volatile profiling of 12 fennel fruit varieties.

Curcumin (CUR) is a symmetrical dicarbonyl compound with antibacterial activity. On the other hand, pharmacokinetic and chemical stability limitations hinder its therapeutic application. Monocarbonyl analogs of curcumin (MACs) have been shown to overcome these barriers. We synthesized and investigated the antibacterial activity of a series of unsymmetrical MACs derived from acetone against Mycobacterium tuberculosis and Gram-negative and Gram-positive species. Phenolic MACs 4, 6 and 8 showed a broad spectrum and potent activity, mainly against M. tuberculosis, Acinetobacter baumannii and methicillin-resistant Staphylococcus aureus (MRSA), with MIC (minimum inhibitory concentration) values ranging from 0.9 to 15.6 mu g/mL. The investigation regarding toxicity on human lung cells (MRC-5 and A549 lines) revealed MAC 4 was more selective than MACs 6 and 8, with SI (selectivity index) values ranging from 5.4 to 15.6. In addition, MAC 4 did not demonstrate genotoxic effects on A549 cells and it was more stable than CUR in phosphate buffer (pH 7.4) for 24 h at 37 degrees C. Fluorescence and phase contrast microscopies indicated that MAC 4 has the ability to disrupt the divisome of Bacillus subtilis without damaging its cytoplasmic membrane. However, biochemical investigations demonstrated that MAC 4 did not affect the GTPase activity of B. subtilis FtsZ, which is the main constituent of the bacterial divisome. These results corroborated that MAC 4 is a promising antitubercular and antibacterial agent.
