Special Issue Information

Dear Colleagues,

One of the major challenges of modern medicine is the effective treatment of many diseases that are still difficult to manage. Despite the commercial availability of a number of therapeutics, their performance is still largely limited. Patients’ chances for recovery are improved by searching for new compounds with specific biological properties, which could become an alternative or a breakthrough therapy. On the other hand, we are witnessing the dynamic development of chemistry, medicinal chemistry, and biochemistry, which are presenting new and innovative solutions for drug discovery.

This Special Issue, “Design, Synthesis, and Analysis of Potential Drugs, 3rd Edition”, aims to showcase the most interesting studies on the design of bioactive molecules that could become effective drugs. Moreover, studies that explore the processes of biotransformation of organic compounds and the organic synthesis of pharmaceutical compounds will be of interest. In addition, it is expected that the chemistry of heterocycles, carbohydrates, and proteins—enzymes in particular—will also be described and discussed in the submitted papers.

I hope that the proposed Special Issue will offer a comprehensive and interesting view of the current research on new potential drugs and be an important source of successful solutions for their modern design.

Abstract

Although the wide variety of bioactivities of curcumin has been reported by researchers, the clinical application of curcumin is still limited due to its poor aqueous solubility. In view of this, a series of dimethylaminomethyl-substituted curcumin derivatives were designed and synthesized (compounds 1–15). Acetate of these derivatives were prepared (compounds 1a–15a). The Mannich reaction and aldol condensation reaction are the main reactions involved in this study. Compounds 6, 10, 12, 3a, 5a, 6a, 7a, 8a, 10a, 11a, 12a, 13a, 14a, and 15a exhibited better in vitro anti-inflammatory activity compared to curcumin in the RAW264.7 cell line. Compounds 5, 1a, 5a, 8a, and 12a exhibited better in vitro antioxidant activity compared to curcumin in the PC 12 cell line. Compounds 11, 13, 5a, 7a, and 13a exhibited better in vitro radiation protection compared to curcumin in the PC 12 cell line. The aqueous solubilities of all the curcumin derivative acetates were greatly improved compared to curcumin. Full article

Abstract

Many new isomeric dipyridothiazine dimers have been presented as molecules with anticancer potential. These compounds were obtained in efficient syntheses of 1,6-, 1,8-, 2,7- and 3,6-diazaphenothiazines with selected alkylaromatic linkers. The structures of these compounds has been proven with two-dimensional spectroscopic techniques (COSY, NOESY, HSQC and HMBC) and high-resolution mass spectrometry (HRMS). In silico analyses of probable molecular targets were performed using the Way2Drug server. All new dimers were tested for anticancer activity against breast cancer line MCF7 and colon cancer line SW480. Cytotoxicity was assessed on normal L6 muscle cells. The tested dimers had high anticancer potential expressed as IC₅₀ and the selectivity index SI. The most active derivative, 4c, showed an IC₅₀ activity of less than 1 µM and an SI selectivity index higher than 100. Moreover, the compounds were characterized by low toxicity towards normal cells, simultaneously indicating a high cytostatic potential. Full article
