An experiment was carried out to investigate the effects of different mineral fertilizers on mineral contents in turmeric rhizomes and soil enzyme activities and soil properties under field conditions in Uzbekistan. The present study is the first report on the impact of mineral fertilizers in turmeric rhizomes and soil enzymes and soil properties in Uzbekistan. The experiment was carried out with four treatments: T1—Control, T2—N75P50K50 kg/ha, T3—N125P100K100 kg/ha, and T4—N100P75K75 + B3Zn6Fe6 kg/ha. Turmeric rhizomes and soil samples were collected from field experiments at the Surkhandarya scientific experimental station of the vegetable, melon crops and potato research institute, Surkhandarya, Uzbekistan. The data showed that T3—the NPK (125:100:100 kg/ha) and T4—the NPK + BZnFe (100:75:75:3:6:6 kg/ha) treatments significantly enhanced K content by 27–21%, Ca content by 43–38%, and P content by 54–17% in turmeric rhizomes as compared to control without fertilizer. A maximum of turmeric rhizome microelements content was recorded with T4, which also resulted in improved Fe, Zn, Cu, Cr, and Mo contents in turmeric rhizomes and mineral contents of soil compared to other treatments. This treatment significantly enhanced active P content by 34%, active K content by 25%, total P content by 62%, total K content by 14%, and the activities of soil urease, invertase, catalase, and phosphatase over those in the control. The present study results suggest that the application of NPK + BZnFe (100:75:75:3:6:6 kg/ha) improves macro and micronutrient contents in turmeric rhizomes and activities of soil enzymes and physicochemical properties of soil.

In this work, we design and then synthesis of new derivatives of nucleosides, oxadiazoline derivatives containing acetylated sugars and α-aminophosphonate derivatives. The synthesized compounds have been elucidated by different spectroscopic analysis, such as, elemental analysis, 13C NMR, infrared (IR) and 1H NMR. The compounds previously synthesized were purified and then tested against breast cancer cells (MCF-7). The results showed that the compounds 5d, 6b, 7a and 9h showed moderate to very high activity against breast cancer, with incidence rates of 78.45 %, 84.60 %, 93.45 % and 95.78 %, respectively. The reference ratio of 5-fluorouracil was inhibitory of 96.02%. The binding potential of synthesized compounds against thymidylate synthase (TS) and Cathepsin B (CB) has been investigated and the compounds 7a and 9h exhibits highly binding with thymidylate synthase (TS) and Cathepsin B (CB).

New Nucleosides, analogues derived from 1, 3, 4-oxadiazole, arylidene analogues and α-aminophosphonate were prepared. Infrared (IR), elemental analysis and 1HNMR elucidated nucleosides; arylidines and phosphonate derivatives. The prepared derivatives were purified and allowed to test against bacteria strains. Phosphonate derivative 12a showed the higher antibacterial against E. coli with inhibition zone 35 mm, P. aeruginosa with inhibition zone 30 and S. aureus with inhibition zone 22 while compounds 4, 6d, 9a, 9c and 12c showed moderate to weak activity against these bacteria species with inhibition zones ranged from 12 mm to 24 mm. The molecular docking studies was applied on compound 12a, which showed the binding at the active DNA Gyrase.

For the first time a finger print analysis via high-performance thin layer chromatography (HPTLC) of Boswellia Sp. Burseraceae was accomplished. A preliminary investigation of the Boswellia Sp. Burseraceae displayed the presence of chemical constituents that could be involved in the production of innovative pharmaceuticals for an array of antiviral, anticancer, and antibacterial uses. Moreover, the finger print analysis would deem useful for establishing HPTLC standardization for natural and herbal photochemical constituents.
