Secondary bonding in dimethylbis(morpholine-4-carbodithioato-κ2S,S′)tin(IV): crystal structure and Hirshfeld surface analysis

Acta Crystallographica Section E: Crystallographic Communications, 2017
The title compound, [Sn(CH3)2(C5H8NOS2)2], has the SnIV atom bound by two methyl groups which lie over the weaker Sn—S bonds formed by two asymmetrically chelating dithiocarbamate ligands so that the coordination geometry is skew-trapezoidal bipyramidal.

Tributyltin Protumorigenic Effects Targeting Prostate Cancer Cell Metabolism, Proliferation, Migration, and Invasion

Environmental Toxicology, EarlyView.
ABSTRACT Prostate cancer (PCa) is an endocrine‐related cancer highly dependent on androgenic signaling. Beyond hormone dependence, extrinsic factors play a significant role in the risk of developing PCa, which raises concern about the influence of environmental compounds such as endocrine‐disrupting chemicals (EDCs). Tributyltin (TBT) is an EDC used in

Tin-Naphthalene Sulfonic Acid Complexes as Photostabilizers for Poly(vinyl chloride)

Molecules, 2021
Poly(vinyl chloride) degrades when exposed to ultraviolet light for long durations; therefore, the photostability of polymeric materials should be enhanced through the application of additives.

Effects of Tributyltin Chloride on Human Neuronal Differentiation and Mice Brain Development

Environmental Toxicology, EarlyView.
ABSTRACT According to the developmental origins of health and disease hypothesis, perinatal exposure to an environmental toxicant during the development of the nervous system could cause a permanent cellular modification that may promote the appearance of neurodegenerative diseases at an older age.

Imposex induction in Stramonita haemastoma floridana (Conrad, 1837) (Mollusca: Gastropoda: Muricidae) submitted to an organotin-contaminated diet

Brazilian Journal of Oceanography, 2006
Marine organisms are affected by organotin compounds due to the cumulative, deleterious effects of these latter. The most evident and well known consequence of organotin contamination is imposex, a hormonal disruption that causes a superimposition of ...
