Definitions
- the present invention is framed in the field of clinical medicine, particularly in the field of oncology and autoimmune diseases such as psoriasis and rheumatoid arthritis. Specifically, the invention provides an improved therapy for said diseases by combining methotrexate with lipophilic statins. STATE OF THE TECHNIQUE
- Methotrexate ((2S) -2 - [(4 - ⁇ [(2,4-diaminopteridin-6-yl) methyl] (methyl) amino ⁇ benzoyl) amino] pentanedioic acid, CAS number 59-05-2, formula I, abbreviated as MTX) is an antimetabolite that has antiproliferative and anti-inflammatory activity by competitively inhibiting the enzyme dihydrofolate reductase (DHFR), an enzyme that regulates the amount of intracellular folate available for the synthesis of S-phase nucleic acids in the cell cycle and prevents conversion from homocysteine to methionine during protein synthesis.
- DHFR dihydrofolate reductase
- MTX is used as a first-line chemotherapeutic for the treatment of some neoplastic diseases, such as osteosarcoma. It is administered in various neoplasms in very high doses (3 to 12 g / m 2 of patient surface), in patients with normal renal function and is administered with hyperhydration (3 l / m 2 of patient surface) and alkalinization. It is also used for the treatment of some inflammatory diseases, among which psoriatic arthritis and rheumatoid arthritis. However, it is a drug that produces on important occasions and severe adverse side effects that condition a high morbi-mortality in patients who use the drug. In some cases it even forces the premature interruption of chemotherapy in a third of patients despite having made an adequate rescue with folinic acid.
- some neoplastic diseases such as osteosarcoma. It is administered in various neoplasms in very high doses (3 to 12 g / m 2 of patient surface), in patients with normal renal function and is administered with hyperhydr
- Acute encephalopathy usually develops in 3% -15% of patients within the first 5 to 14 days after the start of treatment, and may include headache, nausea, vomiting, lethargy, altered mental status, blurred vision, aphasia. , hemiparesis and seizures. In these cases, most patients can resume treatment with MTX without permanent neurological sequelae, although in 10% - 56% they may experience recurrence with reexposure. To this can be added a chronic encephalopathy that develops slowly, can progress, and can permanently damage neurological function.
- a lipophilic statin and an enzyme dihydrofolate reductase (DHFR) inhibitor, such as methotrexate (MTX)

- the maintenance conditions of all cell lines used were 37 ° C in a humidified atmosphere with 5% C0 2 . Tumor lines were obtained from ATCC (American Type Culture Collection) and were grown according to the recommended conditions.
- Osteosarcoma cell lines were cultured with MTX doses of 10, 20, 30, 40, 50 60, 80 and 100 nM and simvastatin at doses of 0.5 ⁇ and 1 ⁇ .
- Cellular survival was quantified by the sulforrodamine B (SRB) technique, which is a non-radioactive, colorimetric assay of spectrophotometric quantification based on the electrostatic binding of SRB to the basic amino acids fixed with trichloroacetic acid (TCA).

- trypan blue staining was used. Trypan blue is a colloid that is introduced into the cells that have tears in the membrane. Thus, the cells that appear in the image, clearly blue, are considered not viable. For this, it is mixed in a 1.5 mL tube, 50 L of trypan blue solution and 50 of cell suspension. The mixture is homogenized and 10 are placed in the Neubauer chamber. Total cells and non-viable cells (stained completely blue) are counted.

- the samples were incubated with RNase (Sigma) to eliminate their RNA content, at the final concentration of 5 mg / ml for one hour at 37 ° C and with proteinase K (Sigma) (20mg / ml) for one hour at 37 ° C.
- AnnexinV-FITC Apoptosis Detection Kit (Ref: 556547, Becton Dickinson Pharmingen TM) was used to detect and quantify the cells under apoptosis conditions.
