Synthesis, in silico pharmacokinetic analysis and anticancer activity evaluation of benzothiazole-triazole hybrids

409-417Over the past decade, a variety of benzothiazole derivatives have been reported with promising anticancer activity. Benzothiazole and its analogues are capable of acting on a number of molecular targets and thus exerting their anticancer activity. To further develop benzothiazole derivatives as anticancer agents, we attempted to design and synthesize a library of benzothiazole-triazole derivatives. The synthesized hybrid compounds have been selected by National Cancer Institute, USA for the in vitro activity evaluation against 60 human cancer cell lines in a one dose screening panel. Most of the synthesized compounds showed 60-80% growth rate against renal cancer cell line UO-31

Ultralight vector dark matter search using data from the KAGRA O3GK run

Among the various candidates for dark matter (DM), ultralight vector DM can be probed by laser interferometric gravitational wave detectors through the measurement of oscillating length changes in the arm cavities. In this context, KAGRA has a unique feature due to differing compositions of its mirrors, enhancing the signal of vector DM in the length change in the auxiliary channels. Here we present the result of a search for U(1)B−L gauge boson DM using the KAGRA data from auxiliary length channels during the first joint observation run together with GEO600. By applying our search pipeline, which takes into account the stochastic nature of ultralight DM, upper bounds on the coupling strength between the U(1)B−L gauge boson and ordinary matter are obtained for a range of DM masses. While our constraints are less stringent than those derived from previous experiments, this study demonstrates the applicability of our method to the lower-mass vector DM search, which is made difficult in this measurement by the short observation time compared to the auto-correlation time scale of DM

Viewpoints from the national consultation on addressing acute malnutrition on mainstreaming community-based program for management of acute malnutrition in India

High burden of acute malnutrition among children less than 5 years is a major public health problem in India. A ”Two-days National Consultation on Addressing Acute Malnutrition” was organized to gather experiences and evidence from 13 states of India on prevention and management of acute malnutrition among children and documenting viewpoints from experts and government counterparts on the same. The consultation centered around five key themes of addressing acute malnutrition: 1) capacity building, 2) strengthening screening, 3) nutritional care of wasting, 4) tracking progress, and 5) scale-up. The paper highlights the experiences and key recommendations around the above key themes. It emerged that there is a need to further accelerate the efforts toward strengthening existing platforms and services to address acute malnutrition among children. Regular trainings of the frontline workers, increased convergence, regular monitoring, and continued service delivery during the pandemic should be undertaken for better outcomes
