The platinum compounds generally are not considered to be hepatotoxic, but cisplatin has been associated with a low rate of serum enzyme elevations during therapy. These elevations are usually mild, self-limited and asymptomatic, rarely requiring dose modification. There have been only rare case reports of clinically apparent liver injury attributed to cisplatin. In one instance, steatosis and necrosis (steatohepatitis) was found by liver biopsy in a patient who developed liver enzyme elevations 4 weeks after starting a regimen of cisplatin. In another instance, hepatocellular liver injury was described. The number of cases of liver injury attributed to cisplatin have been too few to characterize the liver injury clinically. Autoimmune and immunoallergic features have not been described and cases have all been self-limited. Cisplatin is usually given in combination with other antineoplastic agents and adverse events that occur with these combinations cannot always be attributed to cisplatin. In this regard, individual case reports of reactivation of hepatitis B, sinusoidal obstruction syndrome and severe hyperammonemic coma (without liver injury) have been described after chemotherapeutic regimens that include cisplatin and other platinum coordination complexes such as carboplatin and oxaliplatin.
◉ Summary of Use during Lactation:Most sources consider that mothers receiving antineoplastic therapy should not breastfeed, especially with alkylating agents such as cisplatin. Excretion of platinum into milk occurs, but results from case reports are inconsistent. Platinum in milk may increase with repeated courses of chemotherapy. The exact form(s), and toxicity of platinum excreted into breastmilk are also not known. The nursing infant would receive platinum compounds orally rather than intravenously and oral absorption of platinum compounds by infants is not known. It appears that it is not safe to breastfeed after cisplatin chemotherapy, and breastfeeding should probably be discontinued.
Chemotherapy may adversely affect the normal microbiome and chemical makeup of breastmilk. Women who receive chemotherapy during pregnancy are more likely to have difficulty nursing their infant.
◉ Effects in Breastfed Infants:Two women were treated with unspecified doses of cisplatin for treatment of cervical cancer every 2 weeks during pregnancy. They both breastfed their newborn infants. Follow-up examinations of the infants, including Bayley scale test, neurology, and echocardiography at age of 20 and 35 months revealed normal findings.
◉ Effects on Lactation and Breastmilk:A study of adolescent males who had received chemotherapy for childhood malignancies found that having received cisplatin was associated with elevated serum prolactin concentrations. Another study of survivors of testicular cancer found that about 6% of those treated with cisplatin had abnormally high prolactin levels and 2% had abnormally low prolactin levels.
A telephone follow-up study was conducted on 74 women who received cancer chemotherapy at one center during the second or third trimester of pregnancy to determine if they were successful at breastfeeding postpartum. Only 34% of the women were able to exclusively breastfeed their infants, and 66% of the women reported experiencing breastfeeding difficulties. This was in comparison to a 91% breastfeeding success rate in 22 other mothers diagnosed during pregnancy, but not treated with chemotherapy. Other statistically significant correlations included: 1. mothers with breastfeeding difficulties had an average of 5.5 cycles of chemotherapy compared with 3.8 cycles among mothers who had no difficulties; and 2. mothers with breastfeeding difficulties received their first cycle of chemotherapy on average 3.4 weeks earlier in pregnancy. Of the 3 women who received a cisplatin-containing regimen, 1 had breastfeeding difficulties.
therapeutic agents to mitochondria, which synergistically promote mitochondrial ROS production and induce mitochondrial DNAdamage, finally leading to mitochondria‐mediated apoptosis of cancer cells. Our in vitro and in vivo experiments reveal the excellent anticancer efficacy of these prodrugs, underscoring the encouraging outlook of this strategy for effective cancer therapy.

A series of seven diam(m)inebis(carboxylato)dihydroxidoplatinum(IV) and eleven diam(m)inetris(carboxylato)hydroxidoplatinum(IV) complexes with am(m)ine ligands in the trans position was synthesized and characterized by multinuclear 1H, 13C, 15N, 195Pt NMR spectroscopy. IC50 values for all eighteen substances were determined by means of the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide

For the sake to develop novel platinum(IV) complexes to reverse cisplatin (CDDP) resistence, four multifunctional platinum(IV) prodrugs via conjugating chalcones with the related platinum(IV) complexes derived from cisplatin were designed and evaluated for anti-tumor actyivities in vitro and in vivo. Among them, complex 9 exhibited excellent anticancer activities in vitro with IC50 values at the submicromolar
created by the molecular cage in the resultant plasmonic structures led to a strong plasmon coupling, thus inducing great field enhancement inside the nanogaps. More importantly, the embedded molecular cages endowed the formed hotspots with the capability of selectively trapping targeted molecules, offering huge opportunities for many emergent applications. As a demonstration, the hotspots constructed
