White finger millet (WFM) starch was modified by hydrothermal (HS) and microwave (MS) methods. Modification methods had a significant change in the b* value observed in the HS sample, and it caused the higher chroma (∆C) value. The treatments have not significantly changed the chemical composition and water activity (a) of native starch (NS) but reduced the pH value.

Methods: A cross-sectional cohort study was conducted from Jan 2018 to Dec 2018, in patients presenting with thyroid eye disease to orbit and oculoplasty clinic of a tertiary eye care hospital. A total of 105 patients were included in the study.
Structure-activity relationship studies were conducted on Irosustat (STX64, BN83495), the first steroid sulfatase (STS) inhibitor to enter diverse clinical trials for patients with advanced hormone-dependent cancer. The size of its aliphatic ring was expanded; its sulfamate group was N,N-dimethylated, relocated to another position and flanked by an adjacent methoxy group; and series of quinolin-2(1H)-one and quinoline derivatives of Irosustat were explored. The STS inhibitory activities of the synthesised compounds were assessed in a preparation of JEG-3 cells.

Tibolone is a 19-nortestosterone derivative commonly used in hormone replacement therapy. Although tibolone and its 3alpha/beta-hydroxy metabolites exert oestrogenic effects on bone and the vasomotor system, they do not appear to stimulate breast tissue proliferation. It has been proposed that the lack of an oestrogenic effect on breast tissues may result from the inhibition of oestrone sulphatase (E1-STS) in this tissue by tibolone and its metabolites.

The identification of the active pharmacophore required for potent inhibition of steroid sulphatase activity, i.e. an aryl-O-sulphamate structure, has led to the synthesis and testing of a large number of 1-4 ring-based inhibitors.

Additionally, sulphatase inhibition has been proposed to be of potential therapeutic benefit in the immune system and for neuro-degenerative diseases. After the finding that our first highly potent active site-directed steroid sulphatase inhibitor, oestrone-3-O-sulphamate (EMATE), was highly oestrogenic, we proposed non-steroidal coumarin sulphamates such as 4-methylcoumarin-7-O-sulphamate (COUMATE) as alternative non-steroidal steroid sulphatase inhibitors.
