A series of novel 1,3,4-thia(oxa)diazole substituted 2-(2,4-dioxothiazolidine-5-ylidene)-acetamides 3a-c, 4 and 5a-k have been synthesized following the acylation reaction of 2-amino-5-aryl-1,3,4-oxadiazoles, 5-amino-1,3,4-thiadiazole-2-thiol and it’s S-alkylated derivatives with 2-(2,4-dioxothiazolidine-5-ylidene)acetyl chloride in dioxane medium. The functionalization of compounds 3b, 3c, 5d and 5e was carried out on their N3 position under N-alkylation conditions with N-aryl-2-chloroacetamides in DMF/ethanol medium yielded the corresponding 2,4-dioxothiazolidine-3,5-diacetic acid diamides 6a-e and 7a-b. The structures of target compounds were confirmed by using 1H NMR spectroscopy and elemental analysis. The antioxidant activity evaluation in vitro of the synthesized compounds was performed by the method of scavenging effect on 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals. As a result, the highly active compound 4, namely 2-(2,4-dioxothiazolidin-5-ylidene)-N-(5-mercapto-[1,3,4]thiadiazol-2-yl)acetamide was found to be the most efficient candidate among all compounds with a radical scavenging ability of 88.9%, which was comparable that for ascorbic acid (92.7%). The experimentally calculated IC50 value of 43.1 μM for compound 4 was lower than for ascorbic acid (50.5 μM).

More than 82 % of women of reproductive age note pain in the mammary gland. Every fifth woman feels severe pain (mastalgia) and swelling (mastodynia) in the mammary gland. Cyclic mastalgia is combined with hyperprolactinemia. Hyperprolactinemia occurs when dopamine does not suppress pituitary function enough to reduce prolactin release. Agni casti fructus, known for its dopaminergic activity, relieves pain and discomfort in the mammary glands. 50 patients were under observation. Only 10 % of patients felt mild pain, 32 % experienced moderate pain, 50 % assessed it as severe, and 8 % experienced extreme pain. After the treatment, the complete absence of pain was noted by 76 % of patients. The results of the conducted studies indicate a high efficiency of 76 % and the safety of using Agni casti fructus in treating mastalgia and mastodynia. The high efficiency in the treatment of mastalgia and mastodynia with the herbal medicine Agni casti fructus without the additional use of hormonal drugs can be explained by the fact that this drug normalizes the hormonal balance of a woman
