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 Oxaliplatin facilitates tumor-infiltration of T cells and natural-killer cells for enhanced tumor immunotherapy in lung cancer model, published in 2022, which mentions a compound: 41575-94-4, mainly applied to , SDS of cas: 41575-94-4.
Platinum is reported to have adjuvant immune properties, whether oxaliplatin (OXA) could be utilized to synergize with anti-programmed cell death-1 (PD-1) antibody or anti-NKG2D (natural-killer group 2, member D) antibody is investigated. S.c. A549 lung cancer and murine Lewis lung carcinoma (LLC) models were constructed, which were further i.v. injected with platinum-based drugs or concomitant administrated with anti-PD-1 antibody and or anti-NKG2D antibody. The tumor volume and the proportion of myeloid cells (CD45+CD11b+), CD3+T cells and NK (NK1.1+) cells were detected. The relative expression of chemokine (C-X-C motif) ligand 9 (CXCL9), CXCL10 and CXCL11 and C-X-C motif chemokine receptor 3 (CXCR3) was detected with the ELISA, western blot and flow cytometry. The three platinum drugs (cisplatin, DDP; carboplatin, CBP; OXA) showed similar effects to inhibit A549 tumor growth in immune-deficient mice. While OXA exhibited better antitumor efficacy in wild-type mice bearing LLC with downregulated myeloid cells proportion, upregulated concentration of CXCL9, CXCL10 and CXCL11, and upregulated proportion and CXCR3 expression on T cells and NK cells. OXA combined with anti-PD1 or anti-NKG2D synergistically improved tumor growth inhibition and survival. The combination of OXA to anti-PD1 and anti-NKG2D antibodies will provide the most appropriate treatment benefit. Oxaliplatin promotes T cells and NK cells infiltration through the CXCL9/10/11-CXCR3 axis to enhance anti-PD1 or anti-NKG2D immunotherapy in lung cancer.
Although many compounds look similar to this compound(41575-94-4)SDS of cas: 41575-94-4, numerous studies have shown that this compound(SMILES:O=C1C2(CCC2)C(O[Pt]O1)=O.N.N), has unique advantages. If you want to know more about similar compounds, you can read my other articles.
