Momordica charantia (MC) fruit was subjected to phytochemical and pharmacological interaction studies with oral hypoglycemis in NIDDM patients. Phytochemical, chromatographical analysis and extraction of methanolic MC fruit soft (semi-solid form) in CCl4 + C6H6 solvent system yielded 15 diverse chemical constituents--alkaloids, glycosides, aglycone, tannin, sterol, phenol and protein. The CCl4 + C6H6 MC soft extract was used orally in a dose of 200 mg twice daily (BD) for pharmacological interactions with two diversely acting oral hypoglycemic agents--1) metformin BD and 2) glibenclamide BD in 15 patients of either sex (52-65 years of age) of NIDDM. It was observed that with CCl4 + C6H6 MC soft extract plus half doses of metformin or glibenclamide or both in combination caused hypoglycemia greater than that caused by full doses used in the study with 7 days treatment. Conclusively the extract acts in synergism with oral hypoglycemics and potentiates their hypoglycemia in NIDDM.

In this work, the mutual solubilities of sets of organic diluents (CHCl, CH, CHCl, CCl, CH, and n-hexane) with the organic compound ethylene glycol are investigated via gas chromatography (GC). The experimental data measured for these binary organic systems are used to adjust the future nonaqueous systems for the solvent extraction of various metals with ligands. The obtained results showed that the solubility of ethylene glycol decreased in the order CHCl > CH > CHCl > CCl(0%) ≈ CH ≈ n-hexane.

Chlorobenzene (CHCl) is a flammable liquid with high vapor activity, which is a severe threat to the environment and human health. Therefore, it is essential to develop a highly efficient sensor to detect CHCl vapor. Herein, we developed a UiO-66 three-dimensional photonic crystal (3D PC) optical sensor and investigated its sensing properties toward the CHCl vapor.

A primary criterion for the design of polyhedral metal-organic cages is the requirement of geometrically matched pairs of metal ions and ligand moieties. However, understanding the pathway it takes to reach the final polyhedral structure can provide more insights into the self-assembly process and improved design strategies. In this regard, we report two neutral tetrahedral cages with the formulas {[Pd(NPr)PO](L)} () and {[Pd(NPr)PO](L)} () starting from the acetate-bridged cluster {[Pd(NPr)PO](OAc)(OH)}·2(CH)SO () and the respective oxamide precursors (LH: [C(NH)O]) and (LH: (C(NHMe)O]).

Three new metal-organic frameworks (MOFs), {(CHNH)[Ba(TTHA)(NO)(HO)]}·2HO (), {(CHNH)[Ba(HTTHA)(HO)]}·3HO (), and [Ba(TTHA)(NO)(HO)]·2HO () (HTTHA = 1,3,5-triazine-2,4,6-triamineh-exaacetic acid) have been synthesized and characterized. The sensing properties of - were explored with regard to volatile organic compounds (VOCs) by the quartz crystal microbalance (QCM) technique. The results indicated that and have a much higher selectivity and response to chloromethanes (CHCl, CHCl, and CCl) compared with HO, CHOH, CHCHOH, CHCN, (CH)CO, CH, CHCH, CHCHCH, and CHCl at room temperature.
