N-(Phosphonacetyl)-L-aspartic acid, an inhibitor of aspartate transcarbamylase, was administered to 25 patients with advanced cancer by 10-minute infusion daily x 5 consecutive days to determine the toxicity and to look for evidence of therapeutic effect. Planned dose escalations ranged from 100 to
BACKGROUND
Preclinical and clinical data suggest that N-phosphonacetyl-L-aspartic acid (PALA) can augment the cytotoxic effects of 5-fluorouracil (5-FU). In addition, the combination of 5-FU and radiation therapy has been used with success in prolonging survival and providing palliation of symptoms
5-Fluorouracil (FUra) is a clinically useful antineoplastic agent. Preclinical studies suggest that the therapeutic effects of FUra can be enhanced by pretreatment with N-(phosphonacetyl)-L-aspartic acid (PALA), an inhibitor of aspartate transcarbamylase. The objective of treatment with PALA is to
Twenty-eight patients with refractory advanced malignancies were treated with a 24 hr infusion of 5-fluorouracil (5-FU), Leucovorin (LV), and N-(phosphonacetyl)-L-aspartic acid (PALA) weekly. Twenty-seven patients were evaluable for the assessment of toxicity and anti-tumor activity. PALA was
Twenty-eight patients with refractory advanced malignancies were treated with a 24-hour infusion of 5-fluorouracil (5-FU), leucovorin (LV), and N-(phosphonacetyl)-L-aspartic acid (PALA) weekly. Twenty-seven patients were evaluable to assess toxicity and antitumor activity. The PALA was administered
Fifty-two patients with advanced gastrointestinal (GI) malignancies who had not received previous chemotherapy or radiation therapy were randomized to be treated either with 24-hour infusion of weekly fluorouracil (5-FU) or the same plus N-(phosphonacetyl)-L-aspartic acid (PALA). Forty-seven
Although rats and mice do not vomit, these species are widely studied as models of energy balance and sickness behavior. Previous work has shown that rats exhibit similar neuroanatomical activation of brain and visceral afferent pathways following cisplatin chemotherapy compared to vomiting species.
BACKGROUND
Disintegrants are the key excipients administered in tablet formulations to boost the decomposition of the tablet into smaller pieces in the gastrointestinal environment, thereby increasing the available surface area and enhancing a more rapid release of the active

Three hundred thirty-five previously untreated patients with advanced colorectal carcinoma were randomly assigned to treatment with 5-fluorouracil (5-FU) alone, 5-FU plus N-(phosphonacetyl)-L-aspartic acid (PALA), 5-FU plus high-dose thymidine, 5-FU plus levamisole, or 5-FU plus methyl CCNU,
BACKGROUND
Dextromethorphan is an N-methyl-D-aspartic acid antagonist which can attenuate acute pain with few side-effects. In this prospective, randomized, double-blind study of dextromethorphan and intrathecal morphine, we investigated postoperative pain, pruritus, nausea and vomiting in women
BACKGROUND
Postoperative pain from open reduction and internal fixation of mandibular fracture is a serious issue. Amantadine is an N-methyl-D-aspartic acid or N-methyl-D-aspartate (NMDA) receptor antagonist that can be effective against postoperative pain.
OBJECTIVE
The present study examined the
[reaction: see text] Photolysis at 254 nm of neat (no solvent) unsymmetrical diacyl peroxides derived from cyclopropane carboxylic acids and l-aspartic acid generates protected beta-cyclopropylalanines in reasonable yields. Orthogonally protected 3-(trans-2-aminocyclopropyl)alanine (21), a key
Human parechoviruses are known to cause asymptomatic to severe clinical illness predominantly respiratory and gastroenetric infections. Despite their global prevalence, epidemiological studies have not been performed in Pakistan. In this study, we retrospectively analyzed 110 fecal specimen and
