An ultrasound-assisted method facilitated by lemon juice has been developed to synthesize 2-amino-1,3,4-thiadiazole derivatives I (Ar = Ph, 2-methoxy-5-nitrophenyl, pyridin-3-yl, etc.) that could act as potential anticancer agents. Accordingly, a convenient method has been developed for the rapid synthesis of this class of compounds I under a mild and non-hazardous reaction condition in good yields. The methodol. involved the reaction of various acid hydrazides ArC(O)NHNH2 with TMSNCS in the presence of lemon juice in PEG-400 at room temperature (25-30°C) under ultrasound irradiation These compounds I were assessed for their cytotoxic properties against two different metastatic breast cancer cell lines e.g., MDAMB-231 and MCF-7 and subsequently against SIRT1. The 2-amino 1,3,4-thiadiazole derivatives I (Ar = 4-methoxyphenyl, 3-methoxyphenyl, 2,3-dimethoxyphenyl, 2-methoxy-5-nitrophenyl) showed promising growth inhibition of MDAMB- 231 and MCF-7 cell lines and SIRT1 inhibition in vitro.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Naphthalimide-based probe for the detection of hypochlorite in a near-perfect aqueous solution, published in 2019-11-30, which mentions a compound: 3326-71-4, mainly applied to furanamido naphthalimide preparation hypochlorite detection fluorescent sensor; 1,8-Naphthalimide; fluorescent chemosensor; hypochlorite; theoretical calculations, Quality Control of 2-Furoic hydrazide.

A novel fluorescent turn-off sensor JM for hypochlorite was synthesized. JM showed a remarkable selectivity for ClO- over diverse competitive analytes, including reactive oxygen species (ROS), via deprotonation reaction. Detection limit for ClO- turned out to be 0.60μM. Sensor JM successfully determined ClO- in natural water samples with satisfactory recovery. The sensing mechanism of JM to hypochlorite was demonstrated by fluorescent and UV-visible spectroscopy, ESI-mass, NMR titration and TD-DFT calculations

A Schiff’s base derivative was synthesized using a condensation reaction between 8-formyl-7-hydroxy-4-methylcoumarin and furan-2-carbohydrazide that produced marked aggregation-induced emission and had excellent ability to specifically recognize aluminum ions (Al3+). This compound displayed faint fluorescence in the benign solvent DMF, and exhibited obvious green fluorescence following addition of specific amounts of water. Moreover, it exhibited strong blue fluorescence after combination with Al3+ even in the presence of other interfering ions. These exptl. results demonstrated that this derivative could be used as a fluorescence probe for Al3+. The advantages, including significant fluorescence change, high selectivity and sensitivity, and fast response, meant that this probe could be used both to detect Al3+ in water samples and for fluorescence imaging in living cells.
